You and your friend decide throw a scrabble pizza party. You don't know how many pizzas to order, so you want to obtain an estimate of slices each person would eat. You perform a poll of ten randomly selected patrons to see how many slices they each ate. Their responses are denoted X;, i = 1, ..., 10, and X = 10 ELIXi =4.3 82 = 1 5 10 il (Xi - X)' = 2.7Assuming that the X,- s are Lid. normal. construct a 95 confidence interval for the mean of the Xi 5. Enter the lower and upper bounds on the interval [a, b]
