The following information is available for two samples selected from independent normally distributed populations. Complete parts (a) and (b). Population A n = 13 s2 = 57.3 Population B: n = 21 s2 = 20.6 C. a. At the 0.05 level of significance, is there evidence of a difference between o anda? Determine the hypotheses. Choose the correct answer below. O A. Ho: 04 = 02 Hy: 0 +03 O B. Ho:07 so2 Hy: 0} > 0 OD. Ho: 0} +o Hy: 0 OC. He: 07202 Hyo? <o3 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. Ho. There is evidence of a difference between of and 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 o? >o?? What is your statistical decision? The upper-tail critical value of Fis (Round to two decimal places as needed.) What is your statistical decision? V Ho. There is evidence that of > o
