question 9

Essay

The following data contains task completion times, in minutes, categorized according to the gender of the machine operator and the machine used.
 malefemale Machine 1 15,1716,17Machine 214,1315,13 Machine 316,1817,19\begin{array} { l } & \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.
