There is concern about the thickness of bearing plates being produced. If the thickness exceeds 150 mm then the production line must be shut down and the machine recalibrated. Suppose the thickness produced varies considerably throughout a shift, and has a normal distribution with mean µ = 160 mm and standard deviation σ = 10 mm a. What is the probability that the thickness measurement of a single random sample will fail to detect that the machine is out of...
