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

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. $$\begin{array} { l r c r c c } \text { Source } & D \boldsymbol { F } & \boldsymbol { S S } & \boldsymbol { M S } & \boldsymbol { F } & \boldsymbol { p } \\\text { Teacher } & 2 & 56.93 & 28.47 & 1.018 & 0.404 \\\text { Class Size } & 4 & 672.67 & 168.17 & 6.013 & 0.016 \\\text { Error } & 8 & 223.73 & 27.97 & & \\\text { Total } & 14 & 953.33 & & &\end{array}$$
