The following information is available for two samples selected from independent normally distributed populations. Complete parts (a) and (b). Population A: n = 13 Population B: n = 21 s2 = 28.6 s2 = 53.3 a. At the 0.05 level of significance, there evidence of a difference between o and o? Determine the hypotheses. Choose the correct answer below. OA. H:02 203 He: 0 < O C. Họ: G =G H₂:0} #02 OB. Ho: 6 tož H:04 = 2 O D. Hoio so He: o> o Use technology to find the test statistic, FSTAT FSTAT = (Round to two decimal places as needed.) Use technology determine the p-value. p-value = (Round to three decimal places as needed.) Reach a decision. Ho. There is evidence of a difference between aand o.

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 oź > o2? What is your statistical decision? The upper-tail critical value of F is (Round to two decimal places as needed.) What is your statistical decision? Ho. There is evidence that of >o.
