The following table contains information on matched sample values whose differences are normally distributed. Use Table 2. Number Sample 1 Sample 2 1 16 20 2 11 13 3 23 22 4 21 20 5 18 21 6 15 18 7 18 19 8 17 22 a. Construct the 99% confidence interval for the mean difference μD. (Negative values should be indicated by a minus sign. Round all intermediate calculations to at least 4 decimal places. Round your answers to 2 decimal places.) Confidence interval is to b. Specify the competing hypotheses in order to test whether the mean difference differs from zero. H0: μD ≥ 0; HA: μD < 0 H0: μD = 0; HA: μD ≠ 0 H0: μD ≤ 0; HA: μD > 0 c. Using the confidence interval from part a, are you able to reject H0? Yes No
