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. Perform a Scheffe´ Test to determine which means have a
significance difference. Use $\alpha = 0.05$ $\begin{array}{ccc}\hline \text { Group 1}&\text { Group 2 }&\text { Group 3 } \\\hline 11 & 8 & 6 \\12 & 2 & 12 \\13 & 5 & 4 \\15 & 3 & 8 \\9 & 4 & 9 \\8 & 0 & 4 \\\hline\end{array}$
