Create a stochastic model in Excel for a manufacturing operation. The machine is cutting blanks for a forming process. The stock material is circular with normally distributed diameter averaging of 20 mm and a standard deviation of 0.5 mm. The blanks are cut to an average length of 200 mm. The length of the blanks cut are normally distributed with a standard deviation of 3.2 mm. Create and plot a histogram with CDF. The specification for the blanks is to have volume between 59 and 68 cm3. With the current process, what fraction of the blanks are meeting the specification? What changes to the process or equipment would you recommend for 99.7% of the blanks to be within the specification? Consider at least 200 but not more than 1000 parts. Be certain to document the proposed changes on a third worksheet in the workbook.
