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. Choose the correct answer below. a. State the null and alternative hypotheses to test if the population represented by Sample 1 has a mean that is 2.0 units higher than the population represented by Sample 2. Let ud be the population mean of matched-pair differences for Sample 1 minus Sample 2. State the null and alternative hypotheses. O A. Ho: Hd 2.0 CO VOUTAWN - b. Calculate the appropriate test statistic and interpret the results of the hypothesis test using a = 0.05. AWOWAOW 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.) Print Done 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 2.0 units 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.) Interpret the result Since the p-value the significance level, the null hypothesis. There is evidence that the mean of Sample 1 is 2.0 units higher than the mean of Sample 2. d. What assumptions need to be made in order to perform this procedure? O A. The samples are independent, and the distribution of the matched-pair differences between the measurements for the population is approximately uniform if the number of matched pairs is less than 30. O B. The samples are dependent, and the distribution of the matched-pair differences between the measurements for the population is approximately normal if the number of matched pairs is less than 30. O C. The samples are independent, and the distribution of the matched-pair differences between the measurements for the population is approximately normal if the number of matched pairs is 30 or greater. O D. The samples are dependent, and the distribution of the matched-pair differences between the measurements for the population is approximately uniform if the number of matched pairs is 30 or greater. ?
