A New Manager,hired at a Large Warehouse,was Told to Reduce

question 67

Multiple Choice

A new manager,hired at a large warehouse,was told to reduce the 26% employee sick leave.The manager introduced a new incentive program for employees with perfect attendance.The manager decides to test the new program to see if it's better and receives a P-value of 0.06.What is reasonable to conclude about the new strategy using α = 0.05?

• A)We can say there is a 6% chance of seeing the new program having an effect the employee attendance percentage in the results we observed from natural sampling variation.We conclude the new program is more effective.
• B)If the sick leave percentage has not changed,then there is only a 6% chance of seeing the decrease in the sick leave percentage we observed (or lower)from natural sampling variation.At α = 0.05,we reject the null hypothesis that the sick leave percentage has not changed and conclude that the new incentive program is effective.
• C)There is a 6% chance of the new incentive program having no effect the employee attendance percentage.
• D)If the sick leave percentage has not changed,then there is only a 6% chance of seeing the decrease in the sick leave percentage we observed (or lower)from natural sampling variation.At α = 0.05,we fail to reject the null hypothesis that the sick leave percentage has not changed.There is insufficient evidence to conclude that the new incentive program is effective.
• E)There is a 94% chance of the new incentive program having no effect on the employee attendance percentage.
