     Does   training in a memory program affect memory for spontaneously observed events?   A researcher arranged to train four volunteers in a memory program and four   other volunteers served as controls. A week later, as part of their   psychology class, all eight volunteers watched a film showing a bank robbery.   afterward they were questioned about the events. The number of accurate   responses for the participants who had taken the memory course were 20,25,   24, and 23. The number of correct responses for the control group   participants were 14, 22, 18, and 17. Do these results support the contention   that those trained in this particular memory program are more accurate at   recall for spontaneously observed events? (Use the 0.5 significance level.)   (a) Use the five steps of hypothesis testing.
