Design specifications require that a key dimension in a production process measure $110\frac{+}{-}13$ units. In other words, the mean is $110.$ Upper specification $123$ and lower specification $97.$ A process being considered for producing this product has a standard deviation of $4$ units $((10$ points$).$

a$.$ Calculate CPK and comment on the result

b$.$ Suppose the process average shifts to $98($new mean$).$ Calculate the new CPK$,$ comment on the results Please type your answer
