A researcher finds that among 1000 people who said they attend a religious service at least once a week, 35 stopped to help a person with car trouble. Among 1200 people interviewed who had not attended a religious service at least once a month, 24 stopped to help a person with car trouble. At the 0.05 significance level, test the claim that the two proportions are different. Find each: a) Set up (including Null and Alternative Hypothesis)              b) Test Statistic c) P-value           d) Conclusion (reject or accept H0)
