Lemon Corporation, an automobile manufacturer, is trying to determine the source of defects in some of its autos. Rumor has it that on Mondays large numbers of Lemon auto workers are hung over from a weekend of debauchery and are, therefore, more likely to make mistakes on the job.  In order to test the hypothesis of more defects on Mondays, the company draws a random sample of 400 automobiles made by Lemon in the last two years.   In this sample, they...

Problem 3 A manufacturer wants to compare the number of defects on the day shift with the number on the evening shift. A sample of production from recent shifts showed the following defects: Day Shift                     4          7          6          5          8          6 Evening Shift              7          9          6          10        8          11        13        8 The objective is to determine whether the mean number of defects on the night shift is greater than the mean number on the day shift at the 95%...

Motorola used the normal distribution to determine the probability of defects and the number of defects expected in a production process. Assume a production process produces items with a mean weight of 14 ounces. Use Table 1 in Appendix B. The process standard deviation is 0.15, and the process control is set at plus or minus 1 standard deviation. Units with weights less than 13.85 or greater than 14.15 ounces will be classified as defects. What is the probability of...

Motorola used the normal distribution to determine the probability of defects and the number of defects expected in a production process. Assume a production process produces items with a mean weight of 10 ounces. The process standard deviation is 0.1, and the process control is set at plus or minus 2 standard deviations. Units with weights less than 9.8 or greater than 10.2 ounces will be classified as defects. What is the probability of a defect (to 4 decimals)? In...
