Question

There is a group of people. The average height of these people is 67 inches. Is it more likely to pick an individual who is more than 68 inches tall or a sample of four people who average more than 68 inches tall? Or are they probabilities equal? Or is it impossible to tell? You do not have to explain your answer.

C It is impossible to tell

D They are equally likely
