A statistician wants to test for the equality of means in two independent samples drawn from normal populations of people enrolled in a fitness program. However, he will not perform the equal-variance t- test of the difference between the population means if the condition necessary for its use is not satisfied. Using the number of pound lost at the completion of the program, the statistician conducted an F test to determine whether he should use a t-test with equal or unequal variances to compare the two groups. Using the information provided in the printout:
