Consider the following question:
What was the high temperature in Chicago yesterday?
Which BEST describes the question?

A) It is not a statistical question because the data is a single number.

B) It is a statistical question because the answer can be any number.

C) It is a statistical question because the answer is not known.

D) It is a statistical question because the answer is a measurement.


Answers

Answer 1

Answer:

A) It is not a statistical question because the data is a single number.

Step-by-step explanation:

A statistical question is a question that can be answered by collecting data that vary.

What was the high temperature in Chicago yesterday?

This is not statistical as its answer will not vary. It has been specifically asked that what was the HIGH temperature, so its answer will be a single value.

Rather, if it were to be a statistical question, it would have been - What was the temperature in Chicago throughout the day?

So, option A is correct.

Answer 2

A) It is not a statistical question because the data is a single number.

Understanding Statistical Questions

A statistical question is one that anticipates variability in the data and typically requires data collection and analysis. It often involves multiple observations or measurements that could vary.

Analysis of the Question

The question "What was the high temperature in Chicago yesterday?" is asking for a specific value — the high temperature on a particular day in a particular location.

Option A: It is not a statistical question because the data is a single number.

This seems correct because the question seeks one specific value rather than a range of values or a distribution.

Option B: It is a statistical question because the answer can be any number.

This is not quite accurate because, while the temperature could theoretically be any value, the question is asking for a specific single value.

Option C: It is a statistical question because the answer is not known.

The unknown nature of the answer doesn't necessarily make it a statistical question. Many non-statistical questions also have unknown answers that are single specific values.

Option D: It is a statistical question because the answer is a measurement.

Although the answer is a measurement, this alone does not make it a statistical question. It needs to involve data collected with variation.

If you sell 30 items at $200 a piece and your commission rate is 20%, how much commission do you earn

Answers

1200 dollars. have a nice day and I hope that you ace that test!

Answer:

$1200 a

Step-by-step explanation:

You sell 30 items at $200 a piece and your commission rate is 20%

Price of 30 items = 30 × 200 = $6,000

Your commission = 20% × 6,000

                             = [tex]\frac{20}{100}[/tex] × 6,000

                             = 0.20 × 6,000

                             = $1200

You earn $1200 as commission.

Another tent has the perimeter of 7.2 metres. If the width is 1.3 meters, what is the length?

Answers

Hello,

With what we know, let's set up an equation. The equation to find the perimeter of a rectangle is: P = 2( L + W)

We know the perimeter is = 7.2 meters

And we know the width is = 1.3 meters

Let's plug that into the equation.
7.2 = 2(1.3 + L)

Let's then distribute the 2 to what's in the parenthesis.
7.2 = 2.6 + 2L

If we then want to find the length, we need to subtract 2.6 from that side and also subtract it to the other side so that 2L is only left. After you do that, the equation simplifies to:
7.2 - 2.6 = 2L

The next step is to subtract 7.2 to 2.6, which is:
4.6 = 2L

Lastly, we want to get L by itself so we will divide l by 2, to cancel the 2 out, and then we need to also divide the left side with 2 also. And that will get you with: 
4.6/2 = L

After you divide, L = 2.3 meters

Hope this helps! Have a great day =).

4. = (2·5)·12·(-1) = 10·12·(-1) = (-1)·120 = -120 . . . . multiplying by 10 is about the easiest, so it is convenient to identify the factors of 10 and use them first. Again, it is convenient to ignore the sign until the end.

Answers

So we know $8.50 per hour
One-time fee of $15 for uniform
x hours per week

y=8.5x-15

Answer:

The algebraic expression to the model is [tex]8.5x-15[/tex]

Step-by-step explanation:

Consider the provide situation.

You have a summer job at a car wash. you earn $8.50 per hour and are expected to pay a one-time fee of $15 for the uniform.

Let you work for x hours per week and you earn $8.50 per hours, so the money you will earn can be represented as:

8.50 times x or 8.50x

Now you need to pay one time fee of $15 for the uniform.

For the one time fee use a negative sign.

Thus, the required expression is:

[tex]8.50x-15[/tex]

The algebraic expression to the model is [tex]8.5x-15[/tex]

21.95 with a 4.25% sales tax

Answers

Multiply 21.95 by 1.0425
You get approximate 22.88
That's your answer.

Have an awesome day! :)

From your friendly Helper-in-Training, collinjun0827
The overall price for something that costs $21.95 with a 4.25% sales tax is $22.88. This is how to solve it:

21.95 / 100 = 0.2195 (since percentages are hundredths of a whole number, we divide the whole number by 100 to get 1% of the number)

0.2195 * 4.25 = 0.932879 (since what we got is only 1%, we need to multiply that by 4.25 to get 4.25% of 21.95)

Round 0.932879 up to the nearest thousandth (or 0.93)
And add 21.95 to 0.93.

21.95 + 0.93 = $22.88

I hope this helped you! :)

d. false. the spread of a normal distribution is determined by both its mean and standard deviation.

Answers

b. true. the spread of a normal distribution is completely determined by its standard deviation. A normal distribution is defined by 2 values, its mean and it's standard distribution. The standard distribution determines what the shape of the curve looks like. A small distribution causes the curve to be tall and skinny. A large distribution causes the curve to be short and fat. The overall shape is entirely determine by the standard deviation. The exact location of the peak is determined by the mean. So let's look at the options and see why they're right or wrong. a. false. the spread of a normal distribution is completely determined by its mean. * This is exactly wrong. The mean determines where the peak is, the shape is determined by the standard distribution. b. true. the spread of a normal distribution is completely determined by its standard deviation. * This is absolutely correct. c. true. the spread of a normal distribution is completely determined by its median. * Once again, it's swapping the meaning between mean and standard distribution. d. false. the spread of a normal distribution is determined by both its mean and standard deviation. * This is a bit of weasel wording here. But remember, the SHAPE is determined by the standard distribution while the location of the peak is determined by the mean.

A statistics class at wilmington college has 25 students of which 15 are math majors and 10 are business majors. the professor randomly selects five students to work together on a group project. what is the mean of this probability distribution if selecting a business major is defined as a success?

Answers

Final answer:

The mean of this probability distribution is 2.

Explanation:

To find the mean of the probability distribution, we need to calculate the expected value. In this case, the random variable is selecting a business major as a success. So, the probability of selecting a business major is 10/25, or 0.4. The number of successes (business majors) in the group project can range from 0 to 5. Using the formula for expected value:

E(X) = p1 * x1 + p2 * x2 + ... + pn * xn,

where pi is the probability of xi occurring, we can calculate the mean as:

E(X) = (0.4 * 0) + (0.4 * 1) + (0.4 * 2) + (0.4 * 3) + (0.4 * 4) + (0.4 * 5)

E(X) = 2

Therefore, the mean of this probability distribution is 2.

Women's shoe size follow a normal distribution with a mean of size 7.5 and a standard deviation of 1.5 sizes. Using the 68-95-99.7 rule, if a store owner wants to stock shoe that fit. 68% of women, what range of sizes should the owner order

Answers

Given:
μ = 7.5, the population mean
σ = 1.5, the population standard deviation

According to the 68 - 95 - 99.7 rule, 68% of the population data lies within one standard deviation of the population mean.
Therefore the range of sizes that fit 68% of women is
(7.5-1.5, 7.5+1.5) = (6.0, 9.0)

Answer: 6.0 to 9.0

Final answer:

To fit 68% of women, the store owner should stock shoe sizes between 6 and 9.

Explanation:

To determine the range of shoe sizes that the store owner should order in order to fit 68% of women, we can use the 68-95-99.7 rule, which states that for a normal distribution, approximately 68% of the data falls within one standard deviation of the mean.

In this case, the mean shoe size is 7.5 and the standard deviation is 1.5. So, we can calculate the range by adding and subtracting one standard deviation from the mean:

Lower Bound = Mean - Standard Deviation

Upper Bound = Mean + Standard Deviation

Therefore, the owner should stock shoe sizes between 6 and 9 to fit 68% of women.

When going more than 38 miles per hour, the gas mileage of a certain car fits the model y = 43.81 - .395x where x is the speed of the car in miles per hour and y is the miles per gallon of gasoline. Based on this model, at what speed will the car average 15 miles per gallon? (Round to nearest whole number.)

Answers

15= 43.81-.395x
move the 43.81 to the other side by subtracting it on both sides.
-28.81=-.395x
divide -28.81 by -.395 and get x
x=72.9367= 73 miles per hour to get 15 miles per gallon

Answer:

d. 73

The car will average 15 miles per gallon at the speed 73 miles per hour

Step-by-step explanation:

Your equation is: y = 43.81 - 0.395x

We need to solve for x if y = 15

So plug 15 into your equation: 15 = 43.81 - 0.395x

Then rearrange your equation to get the variable by itself and change the sign: 0.395x = 43.81 - 15

Subtract 43.81 - 15 = 28.81

0.395x = 28.81

Then divide both sides of the equation by 0.395

0.395x/0.395 = 28.81/0.395

x = 72.9367088608

Then (Round to nearest whole number.)

Giving you your solution of 73
