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: 15%; 80%; 50; 65%; 30%; 55; 40%; 40#; 30f; 55%; $1.50; 40%; 65; 40%. Assume the underlying distribution is approximately normal. NOTE: If you are using a Student's t-distribution, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.) O Part (a) (i) Round your answer to two decimal places. x= (ii) Round your answer to two decimal places. S = (iii) Enter an exact number as an integer, fraction, or decimal. n= (iv) Enter an exact number as an integer, fraction, or decimal. n-1= O Part (b) In words, define the random variables X and X. O X is the number of coupons on a page, and X is the average number of coupons on a page. O Xis the number of cents off for a coupon, and X is the average number cents off for a sample of coupons.
