Write true or false for the following statement. Usually a sample has fewer members than the population. Choose the correct choice below. OA. True, because a sample usually includes some, but not all, of the items in the population. B. True, because a sample is always a small group from the population. OC. False, because each member can be sampled multiple times allowing the sample to be larger than the population. OD. False, because the sample is equal to the population.
