3. For each of the following sets of two sample variances and sample sizes. (a) compute the Frest statistic, (b) determine the degrees of freedom, (c) obtain the critical F-value for a = 0.05 from Appendix Table 5, (d) state your conclusion with regard to whether or not the sample data provide sufficient evidence to claim that the population variances are not equal, and (e) 10.1 Use a computer spreadsheet program to obtain the exact p-value for the computed Ftest value S3 n1 n2 Etest DFN DFD Ecritical Sig?
