Data Set 37 “Cola Weights and Volumes” in Appendix B includes volumes (ounces) of a sample of cans of regular Coke. The summary statistics are n=36, \( \bar{x} = 12.19 \) oz, s=0.11 oz. Use a 0.05 significance level to test the claim that cans of Coke have a mean volume of 12.00 ounces. Does it appear that consumers are being cheated?### Explanation:- **n**: Sample size = 36- \( \bar{x} \): Sample mean = 12.19 ounces- **s**: Sample standard deviation = 0.11 ounces- **Significance Level**: 0.05The task is to perform a hypothesis test to determine if the actual mean volume is 12.00 ounces, indicating whether consumers might be receiving less product than expected.
