A medical researcher wishes to try three different techniques to lower blood pressure of patients with high blood pressure. The subjects are randomly selected and assigned to one of three groups. Group 1 is given
Medication, Group 2 is given an exercise program, and Group 3 is assigned a diet program. At the end of six
Weeks, each subjectʹs blood pressure is recorded. Find the test statistic F to test the claim that there is no
Difference among the means. $$\begin{array} { c c c }

Quizplus · Accepted Answer

The correct test statistic F to test the claim that there is no difference among the means is 11.095. This is calculated using an ANOVA (Analysis of Variance) test, which compares the means of the three groups to see if at least one is significantly different from the others.
