(Type a whole number. Round to the nearest person as needed.)A plant superintendent has been assigned the task of improving the joint strength of a clutch assembly. The assembly consists of two components: the clutch cup and the drive sprocket. The two components are joined together by means of a brazing operation. The plant superintendent wanted to investigate whether changing the brazing material would affect average braze strength. They decided he would braze one group with pure copper wire and braze another group with the existing copper alloy. One of the two components, the sprocket, is manufactured from powdered metal. The superintendent had observed from past studies that there was a strong relationship between the density of the sprocket and the joint strength of the assembly after brazing. The greater the porosity of the powdered metal sprocket, the more absorption of the braze material takes place, resulting in a weaker bond. They decided to use the known relationship between sprocket porosity and joint strength for setting up a…

- Cholesterol Testing. A large health care organization uses three laboratories for the routine analysis of blood samples. It is important that the three labs provide equivalent test results. To check that, blood samples are obtained from 10 randomly selected individuals; each blood sample is then divided into three blood subsamples of equal volume; and then the three blood subsamples from each person are sent to different labs. For this problem, the analysis is confined to assessing the measurement of the total cholesterol level for a person. The data are in the following table.XYZ Company has the following capacity per month based on the following: 23 working days per month 1 shift operation at 8 hours per shift. 40 minutes break per shift per employee XYZ company produces bicycles and has the following Capacities per process.
