The following information is available for two samples selected from independent normally distributed populations. Complete parts (a) and (b). Population A: n = 21 Population B: n=13 S2 = 44.3 s2 = 37.9 a. At the 0.05 level of significance, is there evidence of a difference between oị and oz? Determine the hypotheses. Choose the correct answer below. O A. Hoio so : Hy: 0-> o Ho: Hy: 0; #o OB. Ho: 0#o Hy: 0; = 0 OD. Ho: 6220 Hy: 0; <o? Oc. Họ G7 = 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 0 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 of >o? 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 o* >o.
