Suppose that the thicknesses of bolts (mm) manufactured by a certain process can be modeled with a normal distribution having µ = 10 and σ = 1.
a. What is the long-run proportion of bolts whose thicknesses are at most 11 mm?
b. In the long run, what proportion of these bolts will have thickness values between 7.5 mm and 12.5Â mm?
c. In the long run, what proportion of these bolts will have thicknesses that exceed 11.5 mm?
