The sweetener sorbitol has fewer calories than sucrose, adds texture to food, is noncarcinogenic, and is very useful for people with diabetes. Surprisingly, this sweetener is also found in children’s cough syrups. Independent random samples of four cough syrups were obtained, and the amount of sorbitol per teaspoon (in grams) was measured. Conduct the appropriate test to determine whether there is any evidence that at least two population mean levels of sorbitol are different
 and include an ANOVA table.

Biodiesel is a specific type of biofuel. It is renewable, burns cleanly, and helps to reduce our dependence on imported diesel fuel. Biodiesel is made from a mixture of agricultural oils, cooking oil, and animal fats. Independent random samples of daily production (in gallons) was obtained from five facilities near Houston, Texas. Use these data to test the hypothesis of no difference in the population mean daily production of biodiesel at these five plants
