Which of the following are true statements?

Solution

ANSWER

B & C

if the F test 2 sample for variances is used to analyze the data and the results are used to conduct a hypothesis test to determinate wheter the population variances are equal or unequal, even if the null hypothesis is rejected it is possible the populations variances are actually equal
