ss

A sample of 49 items from population 1 has a sample variance of 11 while a sample of 40 items from population 2 has a sample variance of 19. We want to test whether the variances of the two populations are equal using alpha = 0.05. The test statistic is (round to two decimal places) the critical value is you don't find the exact DF in the table). We (input two decimal places and use the closest DFs if HO (write reject or failed to reject, lowercase). Therefore, we can conclude that the variances are unequal, lowercase). (write equal or
