question 176

Essay

The following data contains task completion times, in minutes, categorized according to the
gender of the machine operator and the machine used. $$\begin{array} { l c c } & \text { Male } & \text { Female } \\\text { Machine 1 } & 15,17 & 16,17 \\\text { Machine 2 } & 14,13 & 15,13 \\\text { Machine 3 } & 16,18 & 17,19\end{array}$$ The ANOVA results lead us to conclude that the completion times are not affected by an
interaction between machine and gender, and the times are not affected by gender, but they
are affected by the machine. Change the table entries so that there is no effect from the
interaction between machine and gender, but there is an effect from the gender of the
operator.
