Critical Thinking Suppose you take a random sample from a normal population and you want to determine whether there is sufficient statistical evidence to claim that the population variance differs from a corresponding variance specified in a goverment contract. Which type of test is appropriate, a test of one variance or a test of two variances?

The claim is to test whether the population variance is different from government contract variance or not. In the study, the population variance is compared with the fixed variance value. This shows that, using the test of one variance is appropriate.
The test of two variances is used for comparing variances of two populations. This shows that, using test of two variances is not appropriate.
Hence, the test that would be appropriate to determine whether the population variance differs from variance specified in a goverment contract is test of one variance.
