A bottling company needs to produce bottles that will hold 12 ounces of liquid for a local beer maker. Periodically, the company receives complaints that their bottles are not holding enough liquid. To test this claim, the bottling company randomly samples 15 bottles and finds the average amount of liquid held by the 15 bottles is 11.90 ounces and the standard deviation is 0.20 ounces. Calculate the appropriate test statistic to test the null hypothesis.
