The commencement coordinators announced to the Chancellor that students request on average 4 tickets to the graduation ceremonies. It is known from previous years that the standard deviation is 1.2. They take a sample of 200 students and find that the average is actually 4.15. Do a test to determine if there is evidence that the average number of tickets requested is not four at a five percent level of significance. What is the relevant bound of the rejection region
