Question: Science News (February 25, 1995, p. 124) reported a study of 232 people aged 55 or over who had had heart surgery. The patients were asked whether or not their religious beliefs give them feelings of strength and comfort and whether or not they regularly participate in social activities. Of those who said yes to both, about 1 in 50 died within 6 months after their operation. Of those who said no to both, about 1 in 5 died within 6 months after their operation. What is the relative risk of death (within 6 months) for the two groups? Write your answer in a sentence or two that would be understood by someone with no training in statistics.
