Use a 0.05 significance level and conduct a full hypothesis test using the four-step process described in the text. Be sure to state your conclusion. A random sample of 36 cans of cola is obtained and the contents are measured. The sample mean is 12.19 ounces and the standard deviation is 0.11 ounce. Test the claim that the contents of all such cans have a mean different from 12.00 ounces, the amount indicated on the label.
