Question

The main trial in problem 7 is conducted and involves a total of 200 patients. Patients are enrolled and randomized to receive either the experimental medication or the placebo. The data shown below is collected at the end of the study after 6 weeks on the assigned treatment. Test if there is a significant difference in the proportions of hypertensive patients between groups using a=0.05

The table displays the results of a study comparing the effects of an experimental treatment to a placebo on systolic blood pressure, the incidence of hypertension, and the occurrence of side effects.

### Study Results Overview

- **Sample Size**: Each group in the study consisted of 100 participants.

- **Mean (SD) Systolic Blood Pressure**:
  - **Experimental Group**: The mean systolic blood pressure was 120.2 mmHg, with a standard deviation of 15.4.
  - **Placebo Group**: The mean systolic blood pressure was 131.4 mmHg, with a standard deviation of 18.9.

- **Hypertensive Participants (%)**:
  - **Experimental Group**: 14% of participants were hypertensive.
  - **Placebo Group**: 22% of participants were hypertensive.

- **Side Effects (%)**:
  - **Experimental Group**: 6% of participants experienced side effects.
  - **Placebo Group**: 8% of participants experienced side effects.

### Analysis

This data suggests that the experimental treatment was associated with a lower mean systolic blood pressure compared to the placebo. Additionally, the experimental group had a lower percentage of hypertensive participants and fewer reported side effects than the placebo group.
