Question

A study wanted to estimate the improvement in systolic blood pressure for people who walk daily. The study measured the resting systolic blood pressure of the study participants at the beginning of the study and then again after participating in a walking program for three weeks.

Choose the appropriate statistical inference procedure for this scenario.
