A standardized test is given to a sixth grade class and a seventh grade class. The superintendent believes that the variance in performance from the sixth grade class is greater than the variance in performance from the seventh grade class. The sample variance of a sample of 19 test scores from the sixth grade class is 34.66. The sample variance of a sample of 18 test scores from the seventh grade class is 6.03. Test the claim using a 0.1 level of significance. Let σ21 represent the population variance for sixth grade class.
Step 2 of 5 : Determine the critical value(s) of the test statistic. If the test is two-tailed, separate the values with a comma. Round your answer(s) to four decimal places.
