The following two samples were collected as matched pairs. Complete parts (a) through (d) below Pair 6 7 Sample 1 Co Sample 2 a. State the null and altemative hypotheses to test if a difference in means exists between the populations represented by Samples 1 and 2. Let uy be the population mean of matched-pair differences for Sample 1 minus Sample 2. Choose the correct answer below. OA. Ho Ma # 0 OB. Ho Ha20 Hy Ha = 0 H Ha KO O C. Ho Ha = 0 OD. Ho HaSO b. Calculate the appropriate test statistic and interpret the results of the hypothesis test using a = 0.05 The test statistic is . (Round to two decimal places as needed.) The critical value(s) is(are) (Use a comma to separate answers as needed. Round to two decimal places as needed.) Interpret the results of the hypothesis test using a = 0.05. Choose the correct answer below
