\f14. Let X1, X2...., Xin be a random sample from a normal distribution with unknown mean / and standard deviation o = 20. You are performing a hypothesis test to determine whether population mean is greater than 180, and decide to reject H, if the sample mean is greater than 190. a. Determine P(Type I Error). b. If in fact a = 185, determine P(Type II Error)
