The test statistic for testing equality of variances using the F-test is given by the ratio of sample variances, F = s1^2/s2^2. Here, F = 1.19, which is found by dividing the sample variances (6.52/5.48). We then compare this value to the critical value from the F-distribution with (n1-1) = 10-1 = 9 and (n2-1) = 10-1 = 9 degrees of freedom at the 0.05 significance level. The critical value is F0.05(9,9) = 2.39. Since our calculated F-value (1.19) is less than the critical value (2.39), we fail to reject the null hypothesis of equal variances.
