q26 Suppose cereal box weights have a normal distribution with mean 28 oz and standard deviation 2 oz. Which is LARGER, the probability that one box weighs less than 26 ounces or the probability that the average of 49 boxes weighs less than 26 ounces?

P(X-bar <26) is larger

both probabilities are the same.

P(X<26) is larger
