Question
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. A sample of 59 day-shift workers showed that the mean number of units produced was 323, with a population standard deviation of 19. A sample of 67 night-shift workers showed that the mean number of units produced was 333, with a population standard deviation of 27 units.
The test statistic is Z = . (Negative amount should be indicated by a minus sign. Round your answer to 2 decimal places.)
At the .10 significance level, is the number of units produced on the night shift larger?Explanation / Answer
