Question:
Ecril Technologies makes car parts using vacuum formed molds. The President wants the process of creating molds to be reviewed to determine if the life span of the molds, or the rate they have to replace molds, is acceptable. Each mold produces on average 1,459 acceptable parts with a standard deviation of 81. The lower and upper control limits are 1,297 and 1,945 parts respectively. Calculate the Cp and Cpk to determine if the mold making process is capable of producing sufficient parts to specification? Explain your response.
