Generally speaking, would you say that most people can be trusted? A random sample of n. 258 people in Chicago ages 18-25 showed that r₁-40 said yes. Another random sample of n₂ = 287 people in Chicago ages 35-45 showed that r₂- 69 said yes. Does this indicate that the population proportion oftrusting people in Chicago is higher for the older group?
