Fuel Consumption and Cars
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. Use a = 0.05.
