Researchers compared the balance of a sample of elderly (E) patients with that of a separate sample of younger (Y ) patients. They exposed members of each age group to unpredictable noises and measured the amount of forward and backward sway. To test whether the elderly tend to sway more, they should choose which pair of hypotheses?
