No alpha was stated in the question, so use 0.05 (the standard “go to” in statistics). This needs to be halved for the two-tailed test, so use 0.025.Step 5: Find the critical F Value using the F Table. There are several tables, so make sure you look in the alpha = .025 ...
Formula of F-test The test statistic can be obtained by computing the ratio of the two variancesand. The degrees of freedom are(for the numerator) and(for the denominator). Note that, the more this ratio deviates from 1, the stronger the evidence for unequal population variances. ...
