Soft-drink bottler claims that, on average, cans contain 12 oz of soda. Let X denote the actual volume of soda randomly selected from a can. Suppose that it is normally distributed with a mean of 12 oz and a standard deviation of 0.16 oz. Sixteen cans are to be selected and the soda volume determined for each one. Because the distribution is normal, the sampling distribution is also normal. With the bottler's claim correct, what is the probability that the sample contains an average of at least 12.1 oz?
