Use the following information to answer Questions 27 through 29: Researchers evaluated the impact of a new medication adherence program on the control of blood glucose levels among patients with Type 2 diabetes. Each patient had their HbA1c levels (measured in percentage points) tested before and after participating in the 6-month program. Researchers collected paired data from 150 patients and found an average reduction of 0.5 percentage points (i.e., -0.5%) with a standard deviation of 2.81%. 27. What is the 95% confidence interval for the mean of the paired differences in HBA1c levels? Provide a 1-2 sentence interpretation. 28. What is the null value for this comparison? 29. Based on the results above, which of the following statements is true? Choose all that apply and provide 1-2 sentences justifying each selection. I. The p-value for this test is < 0.05. II. The p-value for this test is > 0.05. III. The test statistic for this test is > 2. IV. The test statistic for this test is < 2. V. We do not have enough information to confirm any of these statements. A. I only B. II & III C. I & IV D. I & III E. V only

program. Researchers collected paired data from 150 patients and found an average
reduction of 0.5 percentage points (i.e., -0.5%) with a standard deviation of 2.81%.
27. What is the 95% confidence interval for the mean of the paired differences in HBA1c
levels? Provide a 1-2 sentence interpretation.
28. What is the null value for this comparison?
29. Based on the results above, which of the following statements is true? Choose all that
