Dear R-User, I met the problem to test equality of variance. Two sample units: conjps-c(9.41,10.45,10.78,10.73,11.11,11.12,11.59,11.04,11.63) ms-c(4.11,5.10,5.70,6.46,6.04,6.16, 6.24,6.32,7.33) Then I use the F test to test: •Test Equality of Two Variances F test to compare two variances

Hi Tammy, I'm afraid this is pretty obviously homework, so we can't really do much to help you. It's not a personal thing: just the considered opinion of this list to believe that giving you answers (or even hefty hints) may undermine whatever intent your teacher has in assigning the problem.
