27 For #20 - 29: A researcher would like to evaluate the effectiveness of a pain-relief patch designed for back pain.Prior to testing the patch, each of the patients (n = 7) rated their current level of back pain on a scale from 1 to 10.After wearing the patch for 90 minutes, a second pain rating is recorded. The data in this repeated-measures design%3Dare as follows:PainPainD scoresD2SSvariance ofD=s²dfBeforeAfter74SMDп94n52t = Mp / SMR.33%3D42127.What is your t-statistic? Calculate it with the information given.

Given that; From the table firstly find difference and by using paired t test. Find other parts.

Answered: Prior to testing the patch, each of the…
