H0 16 Ha 16 The sample size is 120 and the population stand

H0: 16 Ha: < 16 The sample size is 120 and the population standard deviation is 5. Use = .05. If the actual population mean is 15, the probability of a Type II error is 0.2912. Suppose the researcher wants to reduce the probability of a Type II error to .10 when the actual population mean is 15. What sample size is recommended?
