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 7 ounces. a. The process standard deviation is 0.15, and the process control is set at plus or minus 1.6 standard deviation s. Units with weights less than 6.76 or greater than 7.24 ounces will be classified as defects. What is the probability of a defect (to 4...

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...
