6. The American Dietetic Association recommends a dietary intake of 2,000 calories per day. A sample of 438 college athletes in a study of obesity report a mean intake of 2,812 calories per day, with a standard deviation of 206 calories. Based on the sample data, is the caloric intake of college athletes greater than the American Dietetic Association’s recommendations? Run the appropriate test at a 5% level of significance.
