A company buys metal fasteners in large lots. The mean shear strength must be at least 10,000 psi in order for the lot to be acceptable. This may be formulated as a hypothesis testing problem with  H0: μ≤10,000 vs H1: μ>10,000. A sample of 10 fasteners is tested, and if the sample mean exceeds 10,500 psi, then H0 is rejected and the lot is accepted. Assume σ=1000 psi. If the true μ=11,000, what is error type II?
