Reference no: EM13102650

A clinical trial is planned to compare an experimental medication designed to lower blood pressure to a placebo. The objective of the study is to assess how systolic blood pressure change untreated over time. Systolic blood pressures are measured at baseline and again 4 weeks later. Before starting the trial, a pilot study is conducted involving 7 participants. Is there a statistically significant difference in blood pressures overtime? Run the test at a 5% level of significance.

Baseline: 120 145 130 160 152 143 126

4 weeks: 122 142 135 158 155 140 130
