In 1965 a national health survey reported that the intake of saturated fat in the diet of middle-aged men had an average of 36 grams per day. Since then numerous advertising campaigns have taken place to emphasize the health risks involved with high levels of dietary saturated fat intake. A physician randomly selected 6 middle-aged men and studied their diet and found the following daily saturated fat intake (in grams) in their diets:

30, 34, 22, 26, 29, 37

Is there evidence that saturated fat intake by middle-aged men has decreased (on the average) since 1965?
