3) A digital camcorder repair service has set a goal not to exceed an average of 5 working days from the time the unit is brought in to the time repairs are completed. a) State the Hypothesis to show the goal is being met. b) To test the hypothesis, the repair service takes a random sample of 12 repair records and recorded the repair time (in days). The data appear in the repair worksheet of the Hypothesis Tests HW data workbook on Moodle. Use JMP to test the hypothesis of part a). c) Using a = 0.05, draw a conclusion for the hypothesis test. Make sure you state your conclusion in the context of the problem. d) What is the smallest value that you can conclude the average repair time is less than at a = 0.05
