Question

Use the Minitab display to test the claims using the significance level of alpha = 0.05. The sample data are the numbers of support beams manufactured by 5 different operators using 5 different machines. Assume that there is no interaction effect from operator and machine. Test the claim that the four operators have the same mean production output. The F -test statistic is The P-value is Is there sufficient evidence to warrant the rejection of the claim that the four machine operators have the same mean production output? A. Yes, B. No Test the claim that the choice of machine has no effect on the production output. The F -test statistic is The P-value is Is there sufficient evidence to warrant the rejection of the claim that the choice of machine has no effect on the production output? A. No B. Yes
