A nationally distributed college newspaper conducts a survey among students nationwide every year. This year, responses from a simple random sample of 204 college students to the question "About how many CDs do you own?" resulted in a sample mean of x = 72.8. Based on data from previous years, the editors of the newspaper will assume that o=7.2. Use the information given to obtain a 95% confidence interval for the mean number of CDs owned by all college students. A) (65.6, 80.0) B) (71.8, 73.8) C) (72.0, 73.6) D) (72.3, 73.3)

Solve the problem. At the Jumping Jack cookie factory, quality assurance inspectors remove broken or otherwise defective cookies from a moving conveyor belt prior to packaging. Based on past studies, the plant manager knows that the inspectors eliminate 98% of the defective cookies at a conveyor belt speed of 9 feet per minute. As the belt speed increases, the factory can produce more cookies per hour, but at the cost of lower quality of the packaged product. Inspectors collect only 60% of defective cookies at a belt speed of 18 feet per minute.
