1. Describe a 5-step hypothesis test for two variances for a particular claim related to your work or life environment. You need to state the claim, define the null and alternate hypothesis, identify the test significance and the test statistic, and state the decision rule that will be used. The decision rule may be based on critical values or on the p-value approach. You do not need to collect data and actually conduct the test calculations unless you wish to do so.
2. Describe a 5-step hypothesis test using any one of the nonparametric tests in your reading material for a particular claim related to your work or life environment.
