Answer Happy

The following information is available for two samples selected from independent normally distributed populations. Complete parts (a) and (b). Population A: n = 16 S2 = 63.2 Population B: n=21 s2 = 12.4 (... a. At the 0.05 level of significance, is there evidence of a difference between o; and 102? Determine the hypotheses. Choose the correct answer below. O A. Hoci so H4:04>02 OC. He: o 20 H:04 <02 B. Ho: 0; = 0 Hq:04 +02 OD. Ho:64 + o H7:04 = 0 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. and Ho. There is V evidence of a difference between of doo 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 07>03? What is your statistical decision? The upper-tail critical value of F is O. (Round to two decimal places as needed.) What is your statistical decision? Ho. There is evidence that of >02.
