The following information is available for two samples selected from independent normally distributed populations. Complete parts (a) and (b). Population A: n = 16 Population B: n = 13 S2 = 30.2 S2 = 49.8 .. a. At the 0.05 level of significance, is there evidence of a difference between of and ok? Determine the hypotheses. Choose the correct answer below. O A. Ho dº so O B. Ho: o so Hy:o tož H1:04 > 02 OC. Ho: o tož OD. Ho: 0zoz H1:04 <o Hy: 0= ož Use technology to find the test statistic, FSTAT FSTAT = (Round to two decimal places as needed.) Use technology to determine the p-value. p-value = (Round to three decimal places as needed.) Reach a decision. V Ho. There is evidence of a difference between of and oz. b. Suppose that you want to perform a one-tail test. At the 0.05 level of significance, what is the upper-tail critical value of F to determine whether there is evidence that of >o? What is your statistical decision? >
