Assume the assumptions for the tests are met and conduct both the sign test and Wilcoxon Signed-Rank test. State your conclusion for the two tests (sign and Wilcoxon) in terms of the problems. If a new process for mining copper is to be put into a full-time operation, it must produce an average of more than 50 tons of ore per day. A 15-day trial period gave the results shown in the accompanying table. Is there significant evidence that on a typical day the mine produces more than 50 tons of ore? Test by using a = .05.
