Question

It has been suggested that daily production of a subassembly would be increased if better lighting were installed and background music and free coffee and doughnuts were provided during the day. Management agreed to try the scheme for a limited time. A listing of the number of subassemblies produced per week before and after the new work environment for each employee follows.

Ho-

Using the Wilcoxon signed-rank test, determine whether the suggested changes are worthwhile. Assume the level of significance is
0.05.
a. State the null and alternate hypotheses.
Answer is complete and correct.
Ho:
Production has not changed
H1:
Production has increased (one tail)
b. State the decision rule. Use the 0.05 significance level.
X Answer is complete but not entirely correct.
Reject Ho if Ts
