Use the data in the given table and the corresponding Minitab display to test the hypothesis. The following
Minitab display results from a study in which three different teachers taught calculus classes of five different
sizes. The class average was recorded for each class. Assuming no effect from the interaction between teacher
and class size, test the claim that the teacher has no effect on the class average. Use a 0.05 significance level. $$\begin{array} { l r l l l l } \text { Source } & \text { DF } & \text { SS } & \text { MS } & F & p \\\text { Teacher } & 2 & 56.93 & 28.47 & 1.018 & 0.404 \\\text { Class Size } & 4 & 672.67 & 168.17 & 6.013 & 0.016 \\\text { Error } & 8 & 223.73 & 27.97 & & \\\text { Total } & 14 & 953.33 & & &\end{array}$$
