# consider the following hypothesis test. H 0 : μ ≥ 10 H a : μ &lt; 10 The sample size is 120 and the population standard deviation is assumed known with σ = 5. Use α = .05. a. If the population mean is 9, what is the probability that the sample mean leads to the conclusion do not reject H 0 ? b. What type of error would be made if the actual population mean is 9 and we conclude that H 0 : μ ≥ 10 is true? c. What is the probability of making a Type II error if the actual population mean is 8?
