Use the two-proportions z-test to perform the required hypothesis test. Assume that independent simple randomsamples have been selected from the two populations. Use the critical-value approach.
-A researcher finds that of 1000 people who regularly attend a religious service, 31 would stop to help a person with car trouble. Of 1200 people interviewed who do not regularly attend a religious service, 22 would stop to help a person with car trouble. At the 0.05 significance level, do the data provide sufficient evidence to conclude that those who regularly attend a religious service are more likely to stop and help a person with car trouble?
