Find the critical value for the hypothesis test, given the following. (Give your answer correct to two decimal places.)
Ha: ó1 > ó2, with n1 = 8, n2 = 10, and á = 0.025
F = 2.24
I did it this way and it comes up wrong 1-0.025=0.975/2=.4875 looked up on z chart and got 2.2 +.04=2.24 but that was wrong
