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

02

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 Ftest of two variances that must be true is:

The two populations are independent of each other.
