An Air Force vase mess hall has received a shipment of 10, 000 gallon size cams of cherries. The supplier claims that the average amount of liquid is 0.25 gallons per can. A government inspector took a random sample of 100 cans and found that the average liquid content to be 0.28 gallons per can with a standard deviation of 0.10. Does this indicate that the supplier’s claim is too low? (Use a 5% level of significance)
