A survey of the mean number of cents off that coupons give was conducted by randomly surveying one coupon per page from the coupon sections of a recent San Jose Mercury News. The following data were collected: 20; 65: 550 ; 65; 30; 55%; 40%; 40; 30%; 55¢; $1.50; 40%; 65; 40%. Assume the underlying distribution is approximately normal. If many random samples were taken of size 14, what percent of the 95% confidence intervals constructed should contain the population mean worth of coupons?
