An FDA representative randomly selects 8 packages of ground chuck from a grocery store and measures the fat content (as a percent) of each package. Assume that the fat contents have an approximately normal distribution. The resulting measurements are given below. Fat Contents (%) 12 18 18 11 17 18 18 16 Step 2 of 2 : Construct a 90 % confidence interval for the true mean fat content of all the packages of ground beef. Round the endpoints to two decimal places, if necessary.
