One of the tree planters on your team is a law student. You'vebeen talking to her (from a safe distance) about how the hypothesistesting process works in psychology and, in particular, about theidea of setting an alpha level to .05 (1 in 20). She is appalledand responds: ``If I made an error one time in twenty there wouldbe so many innocent people in jail it would be a major tragedy. Youpsychologists need to clean up your act and set your alpha level tosomething like one in 100,000 or one in a million''. Explain toyour law student teammate why what she's suggesting would be a badidea.
