Draw Interaction Plots
-A builder has two crews that construct homes. He is interested in determining if there is a difference in the time it takes the crews to build three different styles of homes. The time in days for each crew is given below. What type of interaction is revealed by the interaction plot? Test at $\alpha = 0.05$ .
$\begin{array}{|l|c|c|c|}\hline & \text { Cottage } & \text { Bi-Level } & \text { 2 story } \\\hline \text { Smith } & 27,34,30,35,39 & 25,47,44,30,39 & 28,24,29,32,41 \\\hline \text { Jones } & 46,41,37,26,24 & 31,39,44,45,32 & 43,45,44,36,31 \\\hline\end{array}$

A) No interaction
B) Significant interaction
C) Some interaction
D) Complete interaction
