1. Researchers found that the volume of a sample of 16 cans of Coke has a mean of 12.19 oz with a standard deviation of 1.25 oz. The mean volume of the sample of 14 Pepsi cans has a mean of 12.29 oz with a standard deviation of 1.05 oz. a) Test the claim that the average size of a Coke can is different than a Pepsi can. Use the p-value method and a significance level of 1%. b) Test the claim that the variance of Pepsi cans is less than the variance of Coke cans. Use a 5% significance level and the critical value method.
