QUESTION 10 Nabisco claims that Chip Ahoy Cookies have an x=28.67 chocolate chips per cookie with a SD=2.67. You randomly select 15 cookies from a new bag and carefully remove all the chocolate chips from each of the 36 cookies. You find the mean of the chocolate chips for the 15 cookies is 24.27 chocolate chips per cookie. Calculate the 99% confidence interval UPPER bound for the chocolate chips in your experiment. (round to the nearest hundredth).
