Question 1206152: In swimming, clearly you would like to swim fast, but swimming consistent times is also important. A survey of 32 swims by men on a local university's swim team found a variance of their swimming times was 6 seconds. A similar survey of 27 swims by swimmers at a different university found the variance was 10 seconds. When testing the hypothesis (at the 5% level of significance) that the variances are equal, what is the test statistic? (please round your answer to 2 decimal places, show work) Answer by Theo(13342) (Show Source):
you are looking for difference in variance, but the input requires standard deviation, so you need to enter the square root of the variance.
square root of 6 = 2.449489743.
square root of 10 = 3.16227766.
this is what the inputs look like.
here's a reference on the f-test for equal variance.
