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 66 day-shift workers was 35The meart number of units produced by a sample of 72 night-shift workers was 357. Assume the population standard deviation of the number of units produced is 27 on the day shift and 34 on the night shift. Using the 0.05 significance level, is the number of units produced on the night shift targer? a. State the null and alternate hypotheses. HO: HDay Night: Hi Hay Night OHO: Day Night Day Night O Ho: Day 2 Night: Hai Day Night b. Compute the test statistic (Negative values should be indicated by a minus sign. Round your answers to 2 decimal places) a Test statistic
c. Compute the p-value. (Round your answer to 4 decimal places.) p.value d. What is your decision regarding the null hypothesis? Reject Ho Do not reject Ho e. Using the 0.05 significance level, is the number of units produced on the night shift larger? Yes
