Question

USDA guidelines recommend that no more than 30% of calories should come from fat. A school nurse selected a random sample of meals served by the cafeteria and calculated the percent of calories from fat in each meal. The resulting 90% confidence interval for the true mean percent of calories from fat in school meals is 29% to 39%. Is there convincing evidence that the true percent of calories from fat in all meals served by the cafeteria is greater than the USDA recommendation? Explain.
