In testing the equality of population variance,what assumption(s)should be considered?
A)Independent samples
B)Equal sample sizes
C)Normal distribution of the populations
D)A and B
E)A and C

Question

Quizplus · Accepted Answer

The assumption of independent samples and equal sample sizes is common for many hypothesis tests, but for testing the equality of population variance, the assumption of a normal distribution of the populations is crucial. Therefore, options A and B can be helpful but not essential, while option C is essential for this hypothesis test. Thus, the best combination is options A and C.
