Cans of regular Coke are labeled as containing 12.

Statistics students weighted the content of 10 randomly chosen cans, and found the mean weight to be 12.1.
Assume that cans of Coke are filled so that the actual amounts are normally distributed with a mean of 12 and a standard deviation of 0.09. Find the probability that a sample of 10 cans will have a mean amount of 12.1 at least .

I would've used the CLT approximation, but that's only if the sample was greater than 30 cans, so now I don't know what to do! HELP PLEASE!!
