Extracted text: Assignment After collecting considerable data, the engineers decided to model the variation in shaft diameter as a normal distribution with mean 10.1 mm and standard deviation 2.7 mm. (a) For the next shaft, what is the probability that its diameter is between 8.5 mm and 13.0 mm? (b) According to the normal model, what proportion of the shafts have diameter between 8.5 mm and 13.0 mm? (c) What proportion of the shafts have diameter greater than 15.1 mm?
