Question 4 Suppose a machine manufactures screws whose diameters, D, are normally distributed. The mean diameter and standard deviation of the population are given by u = 3.0 mm and o= 0.1 mm respectively. A screw is considered to be defective if its diameter D 3.1 mm. A sample of 3000 screws are selected randomly. Estimate the number of defective screws in this sample.
