Problem 4E

Five different variations of a bolt-making process are run to see if any of them can increase the mean breaking strength of the bolts over that of the current process. The P-values are 0.13,0.34,0.03,0.28, and 0.38. Of the following choices, which is the best thing to do next?

i. Implement the process whose P-value was 0.03, since it performed the best.

ii. Since none of the processes had Bonferroni- adjusted P-values less than 0.05, we should stick with the current process.

iii. Rerun the process whose P-value was 0.03 to see if it remains small in the absence of multiple testing.

iv. Return all the five variations again, to see if any of them produce a small P-value the second time around.
