Suppose the average weight of a box of cereal is 28 ounces with a standard deviation of 2 ounces. Assume the weights have a normal distribution. Which is smaller? The chance that one box has a weight less than 27.5 ounces, or the chance that 49 boxes have an average weight less than 27.5 ounces? The chance that the average of 49 boxes weighs less than 27.5 ounces is smaller. Both would give the same chance. The chance that one box weighs less than 27.5 ounces is smaller
