A hotel had a problem with people reserving rooms for a weekend and then not honoring their reservations (no-shows). As a result, the hotel developed a new reservation and deposit plan that it hoped would reduce the number of no-shows. One year after the policy was initiated, management evaluated its effect in comparison with the old policy. Use a nonparametric test to compare the records given in the table (p. 425) on the number of no-shows for the 10 nonholiday weekends preceding the institution of the new policy and the 10 nonholiday weekends preceding the evaluation time. Has the situation improved under the new policy? Test at a = .05.
