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
