Approximate intercept is  4,515.33  

Step-by-step explanation:

The intercept of the GPA grades and the first job salary can be determined by using the intercept function in excel spreadsheet.

In order to ascertain the intercept,we apply the intercept formula:

=intercept(known values of y,known values of x)

known values of y are the dependent variables.The first annual salary in this scenario is dependent upon the GPA of the graduate in question

Known values of x are the independent variables upon which the dependent ones rely for their values i.e the GPA itself

As found in the attached,the intercept is  4,515.33  

Answer:

We conclude that we fail to reject [tex]H_0[/tex] as there is not sufficient evidence to warrant support of the claim that less than 10 percent of the test results are wrong.

Step-by-step explanation:

We are given that among 317 tested​ subjects, results from 25 subjects were wrong.

We have to test the claim that less than 10 percent of the test results are wrong.

Let p = proportion of subjects that were wrong.

So, Null Hypothesis, [tex]H_0[/tex] : p = 10%     {means that 10 percent of the test results are wrong}

Alternate Hypothesis, [tex]H_A[/tex] : p < 10%     {means that less than 10 percent of the test results are wrong}

The test statistics that would be used here One-sample z proportion statistics;

                      T.S. =  [tex]\frac{\hat p-p}{\sqrt{\frac{\hat p (1-\hat p)}{n} } }[/tex]  ~ N(0,1)

where, [tex]\hat p[/tex] = sample proportion of test results that were wrong = [tex]\frac{25}{317}[/tex] = 0.08

           n = sample of tested subjects = 317

So, test statistics  =  [tex]\frac{0.08-0.10}{\sqrt{\frac{0.08 (1-0.08)}{317} } }[/tex]

                              =  -1.31

The value of z test statistics is -1.31.

Now, the P-value of the test statistics is given by the following formula;

                P-value = P(Z < -1.31) = 1 - P(Z [tex]\leq[/tex] 1.31)

                              = 1 - 0.9049 = 0.095

Now, at 0.05 significance level the z table gives critical value of -1.645 for left-tailed test. Since our test statistics is more than the critical value of z as -1.31 > -1.645, so we have insufficient evidence to reject our null hypothesis as it will not fall in the rejection region due to which we fail to reject our null hypothesis.

Therefore, we conclude that we fail to reject [tex]H_0[/tex] as there is not sufficient evidence to warrant support of the claim that less than 10 percent of the test results are wrong.

Answer:

Step-by-step explanation:

The degree of 8m^2n^4 is the sum of the exponents of the variables:

  2 + 4 = 6

The monomial has degree 6.

Answer:

Step-by-step explanation:

We would set up the hypothesis test. This is a test of a single population mean since we are dealing with mean

For the null hypothesis,

µ = 25235

For the alternative hypothesis,

µ > 25235

This is a right tailed test.

Since the population standard deviation is not given, the distribution is a student's t.

Since n = 100,

Degrees of freedom, df = n - 1 = 100 - 1 = 99

t = (x - µ)/(s/√n)

Where

x = sample mean = 27524

µ = population mean = 25235

s = samples standard deviation = 6000

t = (27524 - 25235)/(6000/√100) = 3.815

We would determine the p value using the t test calculator. It becomes

p = 0.000119

Since alpha, 0.05 > than the p value, 0.000119, then we would reject the null hypothesis. There is sufficient evidence to support the claim that student-loan debt is higher than $25,235 in her area.

Answer:

Null hypothesis:[tex]\mu \geq 42.3[/tex]  

Alternative hypothesis:[tex]\mu < 42.3[/tex]  

[tex]t=\frac{40.6-42.3}{\frac{2.7}{\sqrt{24}}}=-3.085[/tex]    

The degrees of freedom are given by:

[tex]df=n-1=24-1=23[/tex]  

Then the p value can be calculated with this probability:

[tex]p_v =P(t_{(23)}<-3.085)=0.0026[/tex]  

If we compare the p value and the significance lvel of 0.1 we see that the p value is lower than the signficance level we can reject the null hypothesis and we can conclude that the the assembly time using the new method is faster

Step-by-step explanation:

Information given

[tex]\bar X=40.6[/tex] represent the sample mean for the new method

[tex]s=2.7[/tex] represent the sample standard deviation

[tex]n=24[/tex] sample size  

[tex]\mu_o =42.3[/tex] represent the value that we want to test

[tex]\alpha=0.1[/tex] represent the significance level

t would represent the statistic

[tex]p_v[/tex] represent the p value

System of hypothesis

We want to verify if  the assembly time using the new method is faster, the system of hypothesis would be:  

Null hypothesis:[tex]\mu \geq 42.3[/tex]  

Alternative hypothesis:[tex]\mu < 42.3[/tex]  

The statistic for this case is given:

[tex]t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}[/tex]  (1)  

The statistic would be given by:

[tex]t=\frac{40.6-42.3}{\frac{2.7}{\sqrt{24}}}=-3.085[/tex]    

The degrees of freedom are given by:

[tex]df=n-1=24-1=23[/tex]  

Then the p value can be calculated with this probability:

[tex]p_v =P(t_{(23)}<-3.085)=0.0026[/tex]  

If we compare the p value and the significance lvel of 0.1 we see that the p value is lower than the signficance level we can reject the null hypothesis and we can conclude that the the assembly time using the new method is faster

Answer:

4cm; 1.79 cm.

Step-by-step explanation:

Okay, this question is about the Calculation involving the volume of a box with a square base and a height.

So, the volume of the box = length × width × height ---------------------------(1).

Therefore, we are going to make use of Equation (1) to determine the solution to this question, so that we have;

For Box A; We are given our volume to be equal to 32cm^3, height = 2cm, length and width = x cm.

For Box B = 32 = 2x^2.

x^2 = 16..

x = 4.

Note that Length = width.

For box B=> 32 = 10x^2.

x = √3.2 cm. = 1.79 cm.

Final answer:

The height of Box A with a base area of 32 square centimeters is 1 cm.

Explanation:

To find the height of Box A, we need to use the formula for the volume of a rectangular box, which is V = length * width * height. Given that the base area of Box A is 32 cm2 and assuming that the volume of Box A is equal to the volume of Box B, we can express their volumes as proportional to each other based on their dimensions.

Box A has a volume of 32 cm³ with a base area of 32 square centimeters.

Volume of Box A = Base Area x Height = 32 cm² x Height = 32 cm³

Height of Box A is 1 cm.

Given that $1.50 is the cost of one kilogram of rice and that one kilogram equals about 2.20462 pounds, the cost of one pound of rice will be about $0.68.

To convert the costs from kilogram to pound, you need to know that one kilogram equals about 2.20462 pounds. Hence, if rice costs $1.50 per kilogram, we can calculate the cost per pound by dividing $1.50 by 2.20462.

This results in a cost of approximately $0.68 per pound of rice.

So, if you're looking to purchase a pound of rice under this cost scheme, it would set you back about $0.68.

Final answer:

To construct a 95% confidence interval for the population mean enrollment at community colleges in the United States, we can use the formula: Confidence Interval = sample mean ± (critical value) × (sample standard deviation / √n). Using the provided sample data, the confidence interval is approximately (5,814.61, 9,173.27).

Explanation:

To construct a 95% confidence interval for the population mean enrollment at community colleges in the United States, we can use the formula:

Confidence Interval = sample mean ± (critical value) × (sample standard deviation / √n)

Given the sample enrollment figures, we can calculate the sample mean as 7,493.94 and the sample standard deviation as 6,650.43. The critical value for a 95% confidence level for a normal distribution is approximately 1.96. With n = 35, the sample size, we can substitute these values into the formula to find the confidence interval:

Confidence Interval = 7,493.94 ± (1.96) × (6,650.43 / √35)

Calculating the values, the confidence interval for the population mean enrollment at community colleges in the United States is approximately (5,814.61, 9,173.27).

Answer: Brother = 31, sister = 26

Step-by-step explanation:

first, take 57, and minus the difference of the ages (5) = 52. divide that between both of them, getting 26, and 26. Since the brother is 5 years older, add 5 to one of the 26's and you get 26, and 31.

Check if its correct: 26+31=57

We can make formulas for this.

Assume x=male age and y=female age.

From this problem, we know that x+y=57 and x-5=y since the brother is older. We can do substitution and plug in the second formula into the first.

x+(x-5)=57

2x-5=57     Add like terms (x)

2x=62         Isolate

x=31

Then plug this into the original to find out y.

x+y=57

31+y=57

y=26

Answer:

range: 20

median: 38

Lower quartile and upper quartile: 29 and 42.5

Interquartile range: 13.5

Which value was affected the most: range

The value of the range was mostly affected after the outlier crossed out.

This is determined by calculating all the values before and after the outlier 72.

The range of data is calculated by taking the difference between the highest value and the lowest value of the data set.

Range=maximum value - minimum value

Given a table of data points as 35, 45, 26, 32, 46, 38, 39, 40, 26, 72.

Finding the values given in the list before crossing out the outlier 72:

Range: 72-26=46

Median: 38.5

Arranging in the ascending order

26, 26, 32, 35, 38, 39, 40, 45, 46, 72

Then, median=[tex]\frac{38+39}{2}[/tex]=38.5

Lower quartile: Q1=32

Upper quartile: Q3=45

IQR: Q3-Q1=45-32=13

Finding the values given in the list after crossing out the outlier 72:

The data set now has 9 elements with data points as 35, 45, 26, 32, 46, 38, 39, 40, 26

Range: 46-26=20

Median: 38

Arranging in the ascending order

26, 26, 32, 35, 38, 39, 40, 45, 46

Since odd number of data points, the median is at the middle point which is 38

Lower quartile: Q1=29

[tex]Q_1=\frac{1}{4} (n+1)[/tex] th term (n=9)

Q1=10/4=2.5

So, the median is between 26 and 32 which is 29

Upper quartile: Q3=42.5

[tex]Q_3=\frac{3}{4} (n+1)[/tex] th term (n=9)

Q3=7.5

So, the median is between 40 and 45 which is 42.5

IQR: Q3-Q1=42,5-29=13.5

From these results, it is observed that only the range is affected mostly when outlier 72 is removed.

Step-by-step explanation:

here are 6 possible sequences of removing 3 marbles. Let R be the red marble, B be the blue marble and G be the green marble. The possible sequences are: RBG, RGB, BGR, BRG, GRB and GBR.

Let A denotes Event 1 and B denotes Event 2.

The favorable cases for A are: BGR, BRG, GRB and GBR.

So, P(A) = 4/6 = 2/3.

The favorable cases for B are: RBG, RGB, BRG and GRB.

So, P(B) = 4/6 = 2/3.

The probability of both events happening is P(A \cap B).

Favorable cases for (A \cap B) are BRG and GRB.

Thus, P(A \cap B) = 2/6 = 1/3.

The probability of either of these events happening is P(A \cup B).

Favorable cases for (A \cup B) are RBG, RGB, BRG, BGR, GRB and GBR.

Thus, P(A \cup B) = 6/6 = 1.

Also, P(A \cap B) \neq P(A) P(B).

So, A and B are not independent.

Let y = number of main seats

Let z = number of balcony seats

Theater has 700 seats. Thus;

Total seat equation is;

x + y + z = 700 - - - - (1)

We are told Orchestra seats sell for $ 50, main seats for $ 40, and balcony seats for $ 25 and a gross revenue of $26,250

Thus ;

all seats revenue equation is;

50x + 40y + 25z = 26250 - - - (eq2)

Now, we are told that, when all the main and balcony seats are​ sold, but only half the orchestra seats are​ sold, the gross revenue is $ 22,750

Thus, we have;

½(50x) + 40y + 25z = 22,750

Which gives ;

25x + 40y + 25z = 22,750 ---(eq3)

Using proportional reasoning from the sample survey where 16 out of 60 students favored the aquarium, it's predicted that approximately 192 out of 720 students in the entire school would prefer the aquarium as their favorite field trip.

Explanation:

We can predict the number of students who would choose the aquarium as their favorite field trip by using proportional reasoning based on the sample provided. In the survey, 16 out of 60 students chose the aquarium which gives us the ratio of 16/60 or approximately 0.267 (rounded to three decimal places).

To find out how many out of the entire school population of 720 students would likely choose the aquarium, we multiply the total number of students by this ratio:

(Total number of students) times (Ratio favoring aquarium)
720 times 0.267 = 192

Therefore, we would predict that approximately 192 students in the school would choose the aquarium as their favorite field trip.

Step-by-step explanation:

Note that the sample size given in the question is fifty(50).

The round-off error is then uniformly distributed on the interval (-.5,.5). Which makes us to have a uniform distribution parameter a = -0.5 and b = 0.5.

Step one: look for the mean.

The mean, μ = (a + b)/2 = (- 0.5 + 0.5)/2 = 0. Which means that our mean is zero(0).

Step two: Calculate the standard deviation from the formula below;

Standard deviation,σ = (b - a)/√12.

Standard deviation,σ = (0.5 +0.5)/√12.

Standard deviation,σ = 0.2887.

Step three: Calculate the standard error.

standard error = σ/√n.

standard error = 0.0408

Therefore, the probability,P ;

Probability, P = 1 - P (- 0.1 < X < 0.1 ) = 1 - P (( -0.1 - 0) / 0.041) < Z < (0.1-0) / 0.041) = 1 - P ( -2.45 < Z < 2.45) = 1 -(0.9929 - 0.0071) = 0.0142.

To seed the entire lawn, you will need 11.4 packages of grass seed.

To determine the number of packages of grass seed needed, we need to find the area of the lawn. The area of a rectangle is given by the formula length * width. In this case, the length is 400 feet and the width is 285 feet. Multiplying these values together, we get an area of 114,000 square feet. Now, we can determine the number of packages needed by dividing the area of the lawn by the area covered by one package of seed. Since one package covers 10,000 square feet, we divide 114,000 by 10,000 to get 11.4 packages.

https://brainly.com/question/32426485

#SPJ11

A total of 12 packages needed.

To determine how many packages of grass seed are needed to seed a lawn of 400 feet by 285 feet, follow these steps:

Calculate the lawn's total area by multiplying its length by its width: 400 feet * 285 feet = 114,000 square feet.

Since one 50-pound package of grass seed is enough for 10,000 square feet, divide the lawn's total area by 10,000 square feet to find the number of packages needed: 114,000 square feet / 10,000 square feet per package = 11.4 packages.

Because you can't purchase a fraction of a package, you'll need to round up to the nearest whole number, which means you require 12 packages of grass seed to cover the entire lawn.

It's also important to consider the seeding rate when determining the amount of seed required. However, in this case, the seeding rate is not needed since the question specifies one package covers a set amount of square footage.
