Cans of regular Coke are labeled as containing 12 oz. Statistics students weighed the contents of 8 randomly chosen cans, and found the mean weight to be 12.13 ounces. Assume that cans of Coke are filled so that the actual amounts are normally distributed with a mean of 12.00 oz and a standard deviation of 0.11 oz. Find the probability that a sample of 8 cans will have a mean amount of at least 12.13 oz.
