The accompanying table shows two samples that were collected as matched pairs. Complete parts (a) through (d) below. Click the icon to view the data table. a. State the null and alternative hypotheses to test if the population represented by Sample 1 has a higher mean than the population represented by Sample 2. Let be the population mean of matched-pair differences for Sample 1 minus Sample 2. Choose the correct answer below. OA. Ho Hd 0 OC. Ho Hd <0 20 O E. Ho Hd=0 H: Hd #0 OB. Ho Hd #0 OD. Ho Hd 0 H:0 OF. Ho Hd 0 H:0 b. Calculate the appropriate test statistic and interpret the results of the hypothesis test using = 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. Since the test statistic the critical value(s), the null hypothesis. There is evidence that the mean of Sample 1 is higher than the mean of Sample 2. c. Identify the p-value and interpret the result. p-value= (Round to three decimal places as needed.) The accompanying table shows two samples that were collected as matched pairs.
