Public Health and Nutrition Nondairy creamers (for coffee and tea) contain vegetable fat, cornsyrup solids, casein, and other ingredients. Independent random samples of various nondairy creamers were obtained, and the percentage of fat in a serving size was measured. Is there any evidence to suggest that at least two nondairy creamers have a different population mean percentage of fat per serving? Use a = 0.05. Write a Solution Trail for this problem.
