A machine that fills beverage cans is supposed to put 12 ounces of beverage in each can. The variance of the amount in each can is 0.01. The machine is moved to a new location. To determine whether the variance has changed, 10 cans are filled. Following are the amounts in the 10 cans. Assume them to be a random sample from a normal population. 12.18 11.96 11.77 12.09 12.03 12.03 12.36 12.28 11.85 Perform a hypothesis test to determine whether the variance differs from 0.01. What do you conclude?
