Sparr Investments, Inc., specializes in tax-deferred investment opportunities for its clients. Recently Sparr offered a payroll deduction investment program for the employees of a particular company. Sparr estimates that the employees are currently averaging $100 or less per month in tax-deferred investments. A sample of 40 employees will be used to test Sparr’s hypothesis about the current level of investment activity among the population of employees. Assume the employee monthly tax-deferred investment amounts have a standard deviation of $75 and that a .05 level of significance will be used in the hypothesis test.

- a. What is the Type II error in this situation?
- b. What is the probability of the Type II error if the actual mean employee monthly investment is $120?
- c. What is the probability of the Type II error if the actual mean employee monthly investment is $130?
- d. Assume a sample size of 80 employees is used and repeat parts (b) and (c).

**a.**

To determine
