For: "The diameter of optical fibre produced by a manufacturer is known to be normally distributed, with a mean of .502mm and standard deviation of .0025mm. The specification requires that the diameter of the fibre be equal to .5mm (plus or minus) .005mm. What proportion of the manufacturer's production will fail to meet the specification?" : Do you create a normal distribution curve?
