The problem is asking you to move around the vertices of points A, B, and Y. Once you do that, all you have to do is look at each angle measure and record it. Once again, the sum of all interior angles in a triangle should be 180° no matter what.

13.) The heights (in inches) of males in the United States are believed to be approximately normally

Fantom [35]

Answer:

Option C) 0.830

Step-by-step explanation:

We are given the following in the question:

The heights (in inches) of males in the United States are believed to be approximately normally distributed with mean $\mu$ .

Sample size, n = 25

Sample mean, $\bar{x}$ = 69.72 inches

Standard deviation, $\sigma$ = 4.15 inches

We have to find the standard error of $\bar{x}$ .

Standard error =

$\dfrac{\sigma}{\sqrt{n}} = \dfrac{4.15}{\sqrt{25}} = \dfrac{4.15}{5} = 0.83$

Thus, the standard error of $\bar{x}$ is 0.83 inches.

The correct answer is

Option C) 0.830
