Let μ denote the true average tread life of a certain type of tire. consider testing h0: μ = 30,000 versus ha: μ > 30,000 based on a sample of size n = 16 from a normal population distribution with σ = 1500. a test with α = 0.01 requires zα = z0.01 = 2.33. the probability of making a type ii error when μ = 31,000 is
