question 35

Essay

A diet center wanted to test three different methods for losing weight to determine if the average weight loss (reported in pounds/week) for each method is the same. The results for the three methods are tabulated below. Given that there is a significant difference between the three methods, use the Tukey test to determine if there is a significant difference between each pair of methods. Let $\alpha = 0.05$ .
$\begin{array}{c|c|c}\text { Liquid Diet (A) } & \text { Low-Calorie Diet (B) } & \text { Low-Calorie Diet and Exercise (C) } \\\hline 4 & 6 & 5 \\2 & 1 & 7 \\1 & 2 & 6 \\2 & 6 & 6 \\3 & 4 & 5\end{array}$
