Each player writes a positive integer number on a piece of paper then they simultaneously show their numbers. The player with the greater number wins. Bobby thinks he has a higher probability of winning. Indeed, no matter what number Betty writes, there is only a finite number of possibilities for writing a smaller number but many more possibilities for writing a greater number. Using similar logic, Betty thinks that she has a higher chance to win.

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.
