Assume that cans of cola are filled so that the actual amounts are normally distributed with a mean of 12.00 ounces and a standard deviation of 0.11 ounce.

oWhat is the likelihood (percentage) that a sample of 49 cans will contain a mean amount of at least 12.05 ounces?

oGiven the result in part (a), is it reasonable to believe that the cans are actually filled with a mean of 12.00 ounces? If the mean is not 12.00 ounces, are consumers being cheated?
