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 56 day-shift workers was 338. The mean number of units produced by a sample of 62 night-shift workers was 343. Assume the population standard deviation of the number of units produced on the day shift is 24 and 31 on the night shift. Using the 0.05 significance level, is the number of units produced on the night shift larger? Required: a. State the null and alternate hypotheses. b. Compute the test statistic. (Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.) c. Compute the p-value. NOTE: P-value calculators are available through online search. (Round your answer to 4 decimal places.) d. What is your decision regarding the null hypothesis? multiple choice 2 Reject H0 Do not reject H0 e. Using the 0.05 significance level, is the number of units produced on the night shift larger? multiple choice 3 No Yes
