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)Independent samples and Equal sample sizes
E)Independent samples and Normal distribution of the populations

Question

The best choice is independent samples and normal distribution of the populations. The assumption of equal sample sizes is not necessary for testing the equality of population variance. However, it is important to have independent samples to ensure that the observations are not influenced by each other. Additionally, the assumption of normal distribution is important as tests for equality of variances are often based on the F distribution, which assumes normality of the populations.
