Please complete the following 5-step hypothesis testing procedure in your Learning Teams:
A simple random sample of forty 20-oz bottles of Coke® from a normal distribution is obtained and each bottle is measured for number of ounces of Coke® in the bottle. The sample mean is 19.4 oz with standard deviation of 1.8 oz. Test the claim at an alpha significance level of 5% that on average there is exactly 19.8 oz of Coke® in each bottle.
