Question

When people learn a new task, their performance usually improves when they are tested the next day, but only if they get at least 6 hours of sleep. To test this, the participants learned a visual task on one day, and then were tested on the task the following day. Half of the participants were allowed to have at least 6 hours of sleep and the other half were kept awake all night. Did participants who slept for 6 hours have better recall the following day? Performance scores: n1=15, n2=14 m1=40.8, m2=34 ss1=510, ss2=414 needed, pooled variance estimated standard error t value t grit reject/ fail to reject
