Information Experts has placed you in a group to develop null and alternative hypotheses to help the bank determine which option would provide the best incentive to consumers. Work to develop the null and alternative hypotheses, write a brief memo to the PiggyBank product development team describing your hypotheses and explaining how you arrived at them.
