You may need to use the appropriate appendix table or technology to answer this question. Consider the following hypothesis test. Ho: MZ 10 H₂H 10 The sample size is 120 and the population standard deviation is 5. Use a = 0.05. If the actual population mean is 9, the probability of a type II error 0.2925. Suppose the researcher wants to reduce the probability of a type II error to 0.10 when the actual population mean is 10. What sample size is recommended? (Round your answer up to the nearest integer.)
