Clark Heter is an industrial engineer at Lyons Products. He would like to determine whether there are more units produced on the night shift than on the day shift. The mean number of units produced by a sample of 90 day-shift workers was 363. The mean number of units produced by a sample of 96 night-shift workers was 369. Assume the population standard deviation of the number of units produced is 39 on the day shift and 46 on the night shift. Using the 0.05 significance level, is the number of units produced on the night shift larger? a. State the null and alternate hypotheses. Ho: HDay 2 HNight: H1: HDay HNight O Ho: HDay 2 HNight: H1: HDay = MNight S b. Compute the test statistic. (Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.) Test statistic -7.25 c. Compute the p-value. (Round your answer to 4 decimal places.) p-value
