Suppose A new study was conducted on the effects of sleep on memory retention. Participants were divided into two groups: one group that got a full 8 hours of sleep each night and another group that was kept awake for 24 hours straight. After one week, both groups were tested on their ability to recall a list of words they had studied the previous day.
Can we infer that "The group that got a full 8 hours of sleep performed better on the memory test than the group that stayed awake for 24 hours."? Yes, no, or maybe?
