A researcher finds that of 1000 people who said that they attend a religious service at least once a week, 31 stopped to help a person with car trouble. Of 1200 people interviewed who had not attended a religious service at least once a month, 22 stopped to help a person with car trouble. Is there convincing statistical evidence that the two proportions are different? Use a significance level of 0.05 Test and CI for Two Proportions
