Q4: The diameter of a shaft in an optical storage drive is normally distributed with mean 0.2408 inch and standard deviation 0.0005 inch. The specifications on the shaft are 0.2400 ± 0.001 inch. a) What proportion of shafts conforms to specifications? b) If the process is centered so that the process mean is equal to the target value of 0.2400, then to specifications now? what proportion of shafts conforms
