Prior to distributing a large shipment of bottled water, a beverage company would like to determine whether there is evidence that the true mean fill volume of all bottles di↵ers from 600 ml, which is the amount stated on the labels. Fill volumes are known to follow a normal distribution with standard deviation 2.0 ml. A random sample of 25 bottles is selected. The sample has a mean of 598.8 ml and a standard deviation of 3.0 ml. What is the value of the test statistic for testing the appropriate test of significance?
(A) t= 0.50
(B) z= 2.00
(C) t= 2.00
(D) z= 3.00
(E) t= 3.00
