I'm doing a test now please help!!!!!!
Ann and Tori wanted to estimate the average weight of an Oreo cookie to determine if it was less than advertised (34 grams for 3 cookies). They selected a random sample of 36 cookies and found the weight of each cookie (in grams). The mean weight was 11.3921 grams with a standard deviation of Sx= 0.0817 grams.
Construct and interpret a 90% confidence interval for the true mean weight of an Oreo cookie. Show your calculations and round your interval to 3 decimal places.
