Our soft drink dispensing machine has a fill variance of 0.0324 ounces. Resetting the machine does not appreciably change the variance. After resetting the machine, it is now supposed to dispense about 7.4 ounces of soft drink into the cups. We obtain a random sample of 35 filled cups and determine the mean fill to be 7.53 ounces. Does it appear the resetting device is working properly?
