Next question The following information is available for two samples selected from independent normally distributed populations. Complete parts (a) and (b). Population A n=21 s? =43.1 Population B n=13 s2 = 33.8 a. At the 0.05 level of significance, is there evidence of a difference between of and o? Determine the hypotheses. Choose the correct answer below. O A. He: 02 203 H₂:0} <0? OC. Ho:of so H:02 > OB. He: +63 Ho} 03 OD. Ho: 0 o H:0#o 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 V Ho. There is evidence of a difference between o 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 i evidence that c? >73? What is your statistical decision? The upper-tail critical value of Fis 7. (Round to two decimal places as needed.) What is your statistical decision? 7 Ho. There is evidence that on
