Clark Heste is an industrial engineer at Lyones Products. He would like to determine whether there are more units produced on the night shift than on the day shift. Assume the population standard deviation for the number of units produced on the day shift is 21 and 28 on the night shift. A sample of 54 day-shift workers showed that the mean number of units produced was 345. A sample of 60 night-shift workers showed that the mean number of units produced was 351. At the .05 significance level, is the number of units produced on the night shift larger?

A. Write the null and alternative hypothesis:

B. What is the significance level?

C. Solve for z value

D. Write the decision rule

E. Accept or Reject: Be Very Specific what you plan to do and why.
