Answer:
The correct answer to the following question will be "32 servings".
Step-by-step explanation:
The given values are,
A bag of chips = 24 ounces
Serving size = 3/4 ounces
Servings = ?
Now,
On dividing "24 ounces" by "3/4 ounce", we get
⇒ [tex]\frac{24}{\frac{3}{4}}[/tex]
⇒ [tex]24\times \frac{4}{3}[/tex]
⇒ [tex]8\times 4[/tex]
⇒ [tex]32[/tex]
Thus, the bag of chips contains "32" servings.
Final answer:
To determine the number of servings in a 24-ounce bag of chips with a serving size of 3/4 ounce, divide the total weight by the serving size, resulting in 32 servings.
Explanation:
The student has asked a question about how to calculate the number of servings in a bag of chips given its total weight and the size of each serving. This is a mathematics problem involving division.
To find out the number of servings in a 24-ounce bag of chips where each serving is 3/4 ounce, you divide the total weight of the bag by the weight of a single serving:
Number of servings = Total weight of the bag / Weight of one serving
Number of servings = 24 oz / (3/4 oz)
To divide the fractions, you multiply by the reciprocal of the serving size, which is:
Number of servings = 24 oz × (4/3)
Number of servings = 32
Therefore, there are 32 servings in the 24-ounce bag of chips.
Students in a statistics class are conducting a survey to estimate the mean number of hours each week that students at their college study. The students collect a random sample of 49 students. The mean of the sample is 12.2 hours. The standard deviation is 1.6 hours. Use the T-distribution Inverse Calculator applet to answer the following question. What is the 95% confidence interval for the number of hours students in their college study?
The 95% confidence interval for the number of hours students at the college study weekly, given a sample size of 49, mean of 12.2 hours, and standard deviation of 1.6, is from 11.62 hours to 12.78 hours.
Explanation:In statistics, the 95% confidence interval for the mean number of hours students study in a week can be calculated using the collected data and the t-distribution. Given that the sample size is 49 (n=49), the sample mean(x) is 12.2 hours, and the standard deviation(s) is 1.6 hours, we need to apply the formula for the confidence interval which is x ± t∗(s/√n). The t-value for 95% confidence with 48 degrees of freedom (49-1) can be found using the t-distribution Inverse Calculator applet, which is about 2.01 (it varies slightly depending on the calculator used).
Now, plug in the given values into the formula: 12.2 ± 2.01 * (1.6 / √49), it simplifies to 12.2 ± 0.58. So, the 95% confidence interval for the number of hours students in the college study each week is from 11.62 hours to 12.78 hours.

its $48892.00
Answer:
His salary after 20 years is $48892
Step-by-step explanation:
Kevin started his new job with a salary of $26,550.
We are also given that every year, he receives a 3.1% increase in his salary
So, rate of increase = 3.1%
Formula : [tex]y(t)=y_0(1+r)^t[/tex]
Where y(t)= Amount after t years
[tex]y_0[/tex] = initial amount = 26550
r = rate of increase in decimals = [tex]\frac{3.1}{100}[/tex]
t = time =20
we are supposed to find his salary after 20 years
Substitute the values in the formula :
Salary after 20 years = [tex]26500(1+\frac{3.1}{100})^{20}=48892.00[/tex]

A manufacturer of t-shirts marks a shirt as "irregular" when it has defects such as crooked seams, stains, rips, or holes. A small number of irregular t-shirts are expected as part of the manufacturing process, but if more than 8% of the t-shirts manufactured at a plant are classified as irregular, the manager has to do an investigation to try to find the source of the increased mistakes in the manufacturing process. In order to test whether his plant is making a higher than expected number of irregular t-shirts, the manager of a plant randomly selects 100 t-shirts and finds that 12 are irregular. He plans to test the hypothesis: H0, P = 0.08, versus Ha, p > 0.08 (where p is the true proportion of irregular t-shirts). What is the test statistic
Answer:
The test statistic value is 1.474.
Step-by-step explanation:
In this case we need to determine whether the plant is making a higher than expected number of irregular t-shirts.
If more than 8% of the t-shirts manufactured at a plant are classified as irregular, the manager has to do an investigation to try to find the source of the increased mistakes in the manufacturing process..
The hypothesis for this test can be defined as follows:
H₀: The proportion of irregular t-shirts is 8%, i.e. p = 0.08.
Hₐ: The proportion of irregular t-shirts is more than 8%, i.e. p > 0.08.
The information provided is:
n = 100
X = number of irregular t-shirts = 12
Compute the sample proportion as follows:
[tex]\hat p=\frac{X}{n}=\frac{12}{100}=0.12[/tex]
Compute the test statistic as follows:
[tex]t=\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
[tex]=\frac{0.12-0.08}{\sqrt{\frac{0.08(1-0.08)}{100}}}\\\\=1.47441\\\\\approx 1.474[/tex]
Thus, the test statistic value is 1.474.

What is the mean of 3, 2, 26, 9
Answer:
10
Step-by-step explanation:
3+2=5+26=31+9=40/4=10
Step-by-step explanation:
When finding mean, you have to add up all of the number and divide that answer by the number of numbers used.
3 + 2 + 26 + 9 = 40
Now, we will divide 40 by 4 because there are 4 numbers.
40 / 4 = 10
So, the mean of the set is 10.
A committee consisting of 4 faculty members and 5 students is to be formed. Every committee position has the same duties and voting rights. There are 9 faculty members and 10 students eligible to serve on the committee. In how many ways can the committee be formed
Answer:
The committee can be formed in 31,752 ways.
Step-by-step explanation:
Every committee position has the same duties and voting rights. This means that the order in which the members are chosen is not important to solve this question. So the combinations formula is used.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In how many ways can the committee be formed
4 faculty members from a set of 9
5 students from a set of 10.
Then
[tex]T = C_{9,4} \times C_{10,5} = \frac{9!}{4!(9-4)!} \times \frac{10!}{5!(10-5)!} = 31752[/tex]
The committee can be formed in 31,752 ways.

A math teacher claims that she has developed a review course that increases the scores of students on the math portion of a college entrance exam. Based on data from the administrator of the exam, scores are normally distributed with mu equalsμ=522522. The teacher obtains a random sample of 20002000 students, puts them through the review class, and finds that the mean math score of the 20002000 students is 527527 with a standard deviation of 110110. Complete parts (a) through (d) below. (a) State the null and alternative hypotheses. Let muμ be the mean score. Choose the correct answer below. A. Upper H 0 : mu equals 522H0: μ=522, Upper H 1 : mu not equals 522H1: μ≠522 B. Upper H 0 : mu less than 522H0: μ<522, Upper H 1 : mu greater than 522H1: μ>522 C. Upper H 0 : mu greater than 522H0: μ>522, Upper H 1 : mu not equals 522H1: μ≠522 D. Upper H 0 : mu equals 522H0: μ=522, Upper H 1 : mu greater than 522
Answer: D
H0: μ=522
H1: μ>522
Step-by-step explanation:
The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean. While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.
So, for this case;
The null hypothesis is that the mean score equals to 522
H0: μ=522
The alternative hypothesis is that the mean score is greater than 522.
H1: μ>522
The correct answer is D. [tex]Upper H_0: = 522, Upper H_1 > 522[/tex].
In this scenario, the math teacher is claiming that her review course increases the scores of students on the math portion of a college entrance exam. Therefore, the null hypothesis [tex](H_0)[/tex] should represent the claim that there is no increase in the mean score, which would be that the mean score is equal to the population mean of 522. The alternative hypothesis [tex](H_1)[/tex] should represent the teacher's claim that the mean score has increased, which would be that the mean score is greater than 522.The null hypothesis is a statement of no effect or no difference and serves as the baseline for testing. The alternative hypothesis is what we aim to support; it is a statement that there is an effect or a difference. In this case, we are testing whether the mean score of students after taking the review course is greater than the population mean.Therefore, the correct hypotheses are:- Null Hypothesis [tex](H_0): = 522[/tex] , indicating no increase in the mean score.- Alternative Hypothesis [tex](H_1): > 522[/tex] , indicating an increase in the mean score.This is a one-tailed test because we are only interested in whether the mean score has increased, not whether it has changed at all (which would require a two-tailed test).
