Question

Use the following information to answer the next two exercises. There are two assumptions that must be true in order to perform an$F$ test of two variances.

What is the other assumption that must be true?

Short answer

The two populations are independent of each other.

Step-by-step solution

Given Information

There are two assumptions that must be true in order to perform an $F$test of two variances.

We have to find what is the other assumption that must be true?

Explanation

It is critical that the following be true to run an F test with two variances:

• The two samples are selected from populations that are roughly regularly distributed.
• The two populations are apart from one another.

Therefore, the second assumption of the $F$test of two variances that must be true is:

The two populations are independent of each other.
