Shafts manufactured for use in optical storage devices have diameters that are normally distributed with mean μ = 0.652 cm and standard deviation σ = 0.003 cm. The specification for the shaft diameter is 0.650±0.005 cm.
A) What proportion of the shafts manufactured by thisprocess meet the specifications?B) The process mean can be adjusted through calibration. If the mean is set to 0.650cm, what proportion of the shaftswill meet specification?C) If the mean is set to 0.650cm, what must the standarddeviation be so that 99% of the shafts will meetspecifications?
