Mr. Lochel performed an "honesty" experiment in which he pretended to pick up either a $1 bill or a $100 bill (which was really his own money) off the ground near an unsuspecting individual and then held it out to them and asked if they dropped it. The value of the "found" money was randomly determined by a prior coin toss. At the end of the experiment he compared the proportion of people who claimed the money as their own. What conclusion can be drawn from this study? Explain.

An automobile assembly line operation has a scheduled mean completion time, μ, of 12 minutes. the standard deviation of completion times is 1.6 minutes. it is claimed that, under new management, the mean completion time has decreased. to test this claim, a random sample of 33 completion times under new management was taken. the sample had a mean of 11.2 minutes. assume that the population is normally distributed. can we support, at the 0.05 level of significance, the claim that the mean completion time has decreased under new management? assume that the standard deviation of completion times has not changed.
