Statistics

Question: Foods that have less than .50 gram of trans fat per serving are allowed to list the trans fat content as zero grams on labels. A random sample of 32 foods that list the amount of trans fat as zero grams but contain partially hydrogenated oils (the primary source of added trans fat) were evaluated for the amount of trans fat per serving. The sample mean and standard deviation of trans fat were found to be .34 and .062 gram, respectively. Calculate a 95% confidence interval for the average amount of trans fat per serving in all foods that are listed as having zero grams of trans fat per serving but contain partially hydrogenated oils.
