Linda? Boardman, Inc., an equipment manufacturer in? Boston, has submitted a sample cutoff valve to improve your manufacturing process. Your process engineering department has conducted experiments and found that the valve has a mean ?(mu?) of 10.00 and a standard deviation ?(sigma?) of 0.06. Your desired performance is mu ?= 10.00 plus or minus3 standard? deviations, where sigma ?= 0.070. For the given? information, the process capability index ?(Upper C Subscript pk?) ?= nothing ?(round your response to three decimal? places).
