Cans of regular Coke are labeled as containing $12 \text{ oz}$. Statistics students weighed the contents of 6 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 0.09 oz. Find the probability that a sample of 6 cans will have a mean amount of at least 12.13 oz.
