Reports completed by independent truck drivers indicate that the mean amount of diesel fuel purchased per week is 346 gal, with a standard deviation of 23.6 gal. Truck managers use this information to plan work schedules and to order gasoline supplies. A random sample of 20 independent truck drivers was obtained and their average weekly gas purchases had a sample standard deviation of 11.7712 gal. Is there any evidence to suggest that the true population variance in diesel fuel purchased each week is different from 556.96? State the TS and decision from the test, using α = 0.05.
