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 60 day-shift workers was 334. The mean number of units produced by a sample of 68 night-shift workers was 341. Assume the population standard deviation of the number of units produced on the day shift is 23 and 28 on the night shift. Using the 0.10 significance level, is the number of units produced on the night shift larger? Required: a. State the null and alternate hypotheses. (Click to select) HO: Day z Night H1: Day Night e values should be indicated by a minus sign. Round your answers to 2 decimal places.) HO: Day > Night H1: Day = Night Test statistic c. Compute the p-value. NOTE: P-value calculators are available through online search. (Round your answer to 4 decimal places.) p-value
