Clark Heter is an industrial engineer at Lyons Products. Hewould like to determine whether there are more units produced onthe night shift than on the day shift. The mean number of unitsproduced by a sample of 53 day-shift workers was 355. The meannumber of units produced by a sample of 62 night-shift workers was363. Assume the population standard deviation of the number ofunits produced on the day shift is 24 and 32 on the nightshift.
At the 0.01 significance level, is the number of units producedon the night shift larger?
Is this a one-tailed or a two-tailed test?
