The accompanying data set includes volumes (ounces) of a sample of cans of regular Coke. The summary statisticsare n = 36, x = 12.196 oz, s = 0.101 oz. Assume that a simple random sample has been selected. Use a 0.10significance level to test the claim that cans of Coke have a mean volume of 12.00 ounces. Does it appear thatconsumers are being cheated?Click the icon to view the data set of regular Coke can volumes. Identify the null and alternative hypotheses.Hoμ= 12.00H₁:μ12.00(Type integers or decimals. Do not round.)Identify the test statistic.10.29(Round to two decimal places as needed.)Identify the P-value.0.000(Round to three decimal places as needed.)State the conclusion about the null hypothesis, as well as the final conclusion that addresses the original claim. Decide whether it appears that consumers are being cheated.Reject the null hypothesis. There issufficient evidence at the 0.01 significance level to warrant rejection of the claim that cans of Coke have a mean volume of 12.00 ounces. It does not appearthat consumers are being cheated, because consumers are getting at least 12.00 ounces.
