Question

The overhead reach distances of adult females are normally distributed with a mean of 202.5 cm and a standard deviation of

7.8 cm. Choose the correct answer below.

A. The normal distribution can be used because the mean is large.
B.The normal distribution can be used because the finite population correction factor is small.
C. The normal distribution can be used because the original population has a normal distribution.
D. The normal distribution can be used because the probability is less than 0.5

Answer 1

C. The normal distribution can be used because the original population has a normal distribution.

Explanation:

When the original population has a normal distribution, we can use the normal distribution to solve the exercise.

In this problem, we have that:

The original population are the adult females.

The problem states that:

The overhead reach distances of adult females are normally distributed with a mean of 202.5 cm and a standard deviation of

7.8 cm.

So the correct answer is

C. The normal distribution can be used because the original population has a normal distribution.
