2 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 55 day-shift workers was 342. The mean number of units produced by a sample of 63 night-shift workers was 349. Assume the population standard deviation of the number of units produced on the day shiftis 26 and 32 on the night shin At the 010 significance level, is the number of units produced on the night shift targer? 8 00444 a. Is this a one-tailed or a two-talled test? One-tailed test OTwo-tailed test b. State the decision rule (Negative value should be indicated by a minus sign. Round your answer to 2 decimal places) The contes de repot HO, DUN 2 c. Compute the value of the test statistic (Negative value should be indicated by a minus sign. Round your answer to 2 decimal places.) 5 004333 d. What is your decision regarding He? Do not reject He Reject to 2 Clark Heter is an industrial engineer at Lyons Products.
