- 18. Amertron produces electrical wiring in 100-foot rolls. The quality inspection process involves selecting rolls of wire at random and counting the number of de- fects on each roll. The last 20 rolls examined revealed the following numbers of defects: Roll Number of Defects Roll Number of Defects 1 4 11 2 2 12 5 3 13 5 4 4 14 7 1 15 16 4 8 7 17 8 18 19 4 3 3 10 20 4 a. If the number of defects per 100-foot roll of wire follows a Poisson distribution, what is the estimate of c obtained from these observations? b. Using a normal approximation to the Poisson, what are the three-sigma control limits that you would use to monitor this process? c. Are all 20 observations within the control limits?8.

- What is Accuracy, and Loss function?ANSWER AS BEST AS YOU CAN FOR A THUMBS UP An oriented-strand board manufacturer operated its plant on a 24-hour, 7-day work week with two 12-hours shifts. Shift changes occurred at 8:00 am and 8:00 pm. At approximately 8:30 pm on January 18, 2001, a wet hog, which was located in a wood room, dropped off line and would not operate. The wet hog was used to grind tree bark and wood residue into a wet fuel used in wet-fuel burners in the plant. The wet hog was not essential to the operation of the plant, and whether or not it was operating had no effect on other operations in the plant. An electrician was assigned to repair the hog. At approximately 10:30 pm, he entered the motor control room and opened a 2300-volt motor circuit breaker. He caused an electrical fault in the circuit breaker, apparently by contacting energized parts inside the circuit breaker cubicle, and…Question 1: A company making tires for bikes is concerned about the exact width of its cyclocross tires. The company has a lower specification limit of 22.8 mm and an upper specification limit of 23.2 mm. The standard deviation is 0.15 mm and the mean is 23 mm. What is the process capability index (Cpk) for the process? Question 2: Consider again that the company making tires for bikes is concerned about the exact width of its cyclocross tires. The company has a lower specification limit of 22.8 mm and an upper specification limit of 23.2 mm. The standard deviation is 0.15 mm and the mean is 23 mm. What is the probability that a tire will either be too wide or too narrow?
