In the analysis by using excel test F-test test is not needed because both sides are negative, see one side is enough for P-vlue. Summary1 if accepted. The main assumption when the value of P-vlue is greater than the value that a given significance level, that is, the variance of a population, both groups did not differ. Thus, the test must be done by using t-test.Samples the test statistic follows.Command in excel program is ..........Case 2, the main hypothesis, when decline P-vlue value less than the value a given significance level, that is, the variance of a population, both groups differ. Thus, the test must be done by using t-test.Samples the test statistic follows.Command in excel program is ..........
