Quizplus · Accepted Answer

To test the hypothesis that the population variances are equal, we use the F-test. The formula for the test statistic is F = s1^2/s2^2, where s1^2 is the sample variance of sample 1 and s2^2 is the sample variance of sample 2. In this case, we have s1^2 = 7.2 and s2^2 = 3.0, so F = 7.2/3.0 = 2.4. Therefore, the test statistic for this problem equals 2.4, which is choice C.
