Answers

Answer:

D. The mean would decrease as there is less variability in the data.

Step-by-step explanation:

So, let’s find the mean with all of those numbers. First of all we should order them from least to greatest.

11.9, 12.0, 12.3, 12.3, 13.5, 16.0

We add them all up, and get 78! Once we get this total, we must divide it by how many numbers there are! There are six numbers, so 78/6.

78/6 is equal to 13. So the mean for all those numbers is 13.

Now let’s find the mean if we cross out the greatest and least numbers, the greatest number is 16.0, and the least number Is 11.9.

So, our new data set is:

12.0, 12.3, 12.3, 13.5

Add those all up to get 50.1

Divide the total by the numbers we got left, which is 4!

50.1/4 is equal to 12.525.

So the mean of our new data set is 12.525!

So that’s how I got the answer, have a nice day! Please tell me if I’m wrong!

12.525 < 13

Answers

Answer:

what is the MAD??????????

Step-by-step explanation:

Answer:

Answer depends on the data (not provided in your question)

Step-by-step explanation:

MAD stands for mean absolute deviation. The definition gives clues as to how to find it.

Deviation refers to how far a number is from the mean (average) of the data

Example: For the data -12, 4, 12, 16, the mean of the data is (-12+4+12+16)/4 = 5.

Data Absolute Deviation from mean

-12 |-12 - 5| = 17

4 |4 - 5| = 1

12 |12 - 5| = 7

16 |16 - 5| = 11

Mean Absolute Deviation (MAD)

(17 + 1 + 7 + 11) / 4 = 9

V = 252 m³

Step-by-step explanation:

Formula for volume of a triangular prism = base area × height of prism

We are given the height (H) of the prism = 9 m

Let's find the base area using the figure of the base that is shown above with the dimensions:

Base area = ½*bh

b = 14 m

h = 4 m

Base area = ½*14*4

= 28 m²

✅Volume of the triangular prism = 28 × 9

Regardless of age, about 20% of American adults participate in fitness activities at least twice a week. A random sample of 100 adults over 40 years old found 15 who exercised at least twice a week. Is this evidence of a decline in participation after age 40? Use α = .05. a) Write test hypothesis b) Compute test statistic. c) Apply any method to draw conclusion.

Answers

Answer:

The null hypothesis is [tex]H_0: p = 0.2[/tex]

The alternate hypothesis is [tex]H_a: p < 0.2[/tex]

The p-value of the test is 0.1056 > 0.05, which means that there is not evidence of decline in participation after age 40 using α = 0.05.

Step-by-step explanation:

20% of American adults participate in fitness activities at least twice a week. Test if there is evidence of a decline in participation after age 40.

At the null hypothesis, we test that the proportion is of 0.2, so:

[tex]H_0: p = 0.2[/tex]

At the alternate hypothesis, we test if the proportion is less than 0.2, indicating a decline. So

[tex]H_a: p < 0.2[/tex]

The test statistic is:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.

20% is tested at the null hypothesis:

This means that [tex]\mu = 0.2, \sigma = \sqrt{0.2*0.8}[/tex]

A random sample of 100 adults over 40 years old found 15 who exercised at least twice a week.

This means that [tex]n = 100, X = \frac{15}{100} = 0.15[/tex]

Test statistic:

[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]

[tex]z = \frac{0.15 - 0.2}{\frac{\sqrt{0.2*0.8}}{\sqrt{100}}}[/tex]

[tex]z = -1.25[/tex]

The probability of being born any day of the year is 1 or more specifically: 365/365. Since Person B must be born on the same day as Person A their probability is 1/365

Answer:

Person A can be born on any day of the year since they’re the first person we’re asking. The probability of being born any day of the year is 1 or more specifically: 365/365.

Since Person B must be born on the same day as Person A their probability is 1/365.

We want both of these events to happen so multiply the probabilities:

365[tex] \frac{365}{365} . \frac{1}{365} = 0.0027[/tex]

So you have a 0.27% chance of walking up to a stranger and discovering that their birthday is the same day as yours.

Answer:

$129,600

Step-by-step explanation:

Given that

The return percentage is 7.5%

And, the monthly net is $810

We need to find the property listed price

Since we assume that the return percentage is on annual basis

So, for monthly, it is

= 7.5% ÷ 12

= 0.625%

Now the property listed price is
