Susаn is in chаrge оf quаlity cоntrоl at a small fruit juice bottling plant. Each bottle produced is supposed to contain exactly 12 fluid ounces. Susan decided to test this by randomly sampling 30 filled bottles and carefully measuring the amount of juice inside. She will recalibrate the machinery if the average amount of juice per bottle differs from 12 oz at the 1% significance level. The sample of 30 bottles has an average of 11.92 oz per bottle and a standard deviation of 0.26 oz. Write the null and alternate hypothesis Susan should run. What is the p value of the test. What assumptions do you need to run the test? What is the conclusion?
