Design specifications require that a key dimension on a productmeasure 101 ± 8 units. A process being considered for producingthis product has a standard deviation of five units.
a. What can you say (quantitatively) regardingthe process capability? Assume that the process is centered withrespect to specifications. (Round your answer to 4 decimalplaces.)
Process capability index
b. Suppose the process average shifts to 98.Calculate the new process capability. (Round your answer to4 decimal places.)
New process capability index
c. What is the probability of defective outputafter the process shift? (Use Excel's NORM.S.DIST()function to find the correct probability. Round "z" values to 2decimal places. Round probabilities to 4 decimal places(0.####).)
