A clinical trial is conducted to test a new medication designed to lower systolic blood pressure (SBP). Participants are randomly assigned to receive the new medication or a placebo. The outcome is clinically significant SBP reduction after 30 days. The data are shown below. Compute the totals. (1pt)

    3. 0.3231
    4. 0.175
    5. Some other answer (indicate):

  1. Generate a 90% confident interval for the true proportion of people experiencing a significant reduction in SBP given they received the new medication. (4pts)

    2. (0.2943, 0.4391)
    3. (0.3155, 0.4179)
    4. (0.2684, 0.465)
    5. Some other answer (indicate):

  1. Estimate the risk difference in significant SBP reductions for the participants who received the new medication versus those that received the placebo and indicate your answer: (1pt)
    1. 0.3538
    2. 0.0958
    3. 0.1719
    4. 0.1917
    5. Some other answer (indicate):

  1. Generate a 95% confidence interval for the difference in proportions of participants experiencing a significant reduction in SBP for the participants who received the new medication versus those that received the placebo and indicate your answer: (4pts)
    1. (0.1856, 0.1978)
    2. (0.0819, 0.3015)
    3. (-0.014, 0.2056)
    4. (0.244, 0.4636)
    5. Some other answer (indicate):

  1. True or False: There is a significant difference in the proportions of participants experiencing a significant reduction in SBP for the participants who received the new medication versus those that received the placebo: (1pt)
    1. True
    2. False

A clinical trial is planned to compare an experimental medication designed to lower blood pressure to a placebo. Before starting the trial, a pilot study is conducted involving seven participants. The objective of the study is to assess how systolic blood pressures change over time if left untreated. Systolic blood pressures are measured at baseline and 4 weeks later. Is there a statistically significant difference in blood pressures over time? Run the test at a 5% level of significance. baseline-120...
