Next question 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 s? = 57.9 s2 = 22.3 a. At the 0.05 level of significance, is there evidence of a difference between of and oz? Determine the hypotheses. Choose the correct answer below. O A. Hoof so H4:07>03 OC. Heinzo H,: 0<o OB. H.: 0; #o H: 67 = 63 OD. H: 01-03 H, 04+02 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 V 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 of >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 o; >o
