An experiment has been conducted to examine main and interactive effects of factor A (keyboard configuration, 3 levels) and factor B (word processing package, 2 levels). Each cell consists of two replications, representing the number of minutes each of two secretaries randomly assigned to that cell required to type a standard document.
Interpret the accompanying computer output for this study, including your conclusion (use the 0.05 level) for each null hypothesis associated with the experiment.
