Design specifications require that a key dimension on a product measure 100 ± 11 units. A process being considered for producing this product has a standard deviation of four units.

a. What can you say (quantitatively) regarding the process capability? Assume that the process is centered with respect to specifications. (Round your answer to 4 decimal places.)

b. Suppose the process average shifts to 90. Calculate the new process capability. (Round your answer to 4 decimal places.)

c. What is the probability of defective output after the process shift? (Use Excel's NORM.S.DIST() function to find the correct probability. Round "z" values to 2 decimal places. Round your answer to 4 decimal places.)

Samples of n =5 units are taken from a process every hour. The x̄ and R̄ values for a particular quality characteristic are determined. After 25 samples have been collected, we calculate x̄ = 20 and R̄ = 4.56. (a) What are the three- sigma control limit for x̄ and R? (b) Both charts exhibit control. Estimate the process standard deviation. (c) Assume that the process output is normally distributed. If the specifications are 19 ± 5, what are your...
