Thecampus Housing administration instituted a “fee and finesystem” that encourages students to clean their apartmentswhen they vacate them. This should shorten the cleanup andredecorating time. A sample of 15 apartments had a mean cleanup andredecorating time of 14.5 hours with a standard deviation of 1.5hours. Does use of the “fee and fine system” decreasethe cleanup and redecorating time? Follow the five-step hypothesistesting procedure using the 0.05 significance level.
