13. A new assembly-line procedure to increase production has been suggested by Mr. Mump. To test whether the new procedure is superior to the old procedure, a random sample of 15 assembly line workers was selected. The number of units produced in an hour under the old procedure is determined, then the new Mump procedure was introduced. After an appro- priate break-in period, their production was measured again. The results were: Production Production Employee Old System Mump Method Employee Old System Mump Method ABCDEFGH 60 64 87 84 40 52 80 80 59 58 K 56 30 37 L 21 70 71 M 99 108 78 83 N 50 43 46 0 56 RUNG 57 21 56 62 40 52 At the .05 significance level, can we conclude the production is greater using the Mump method? a. State the null and alternate hypotheses. b. State the decision rule. c. Arrive at a decision regarding the null hypothesis.
