Generally speaking, would you say that most people can be trusted? A random sample of n₂ = 240 people in Chicago ages 18-25 showed that r₂ = 46 said yes. Another random sample of n₂ = 273 people in Chicago ages 35-45 showed that ₂73 said yes. Does this indicate that the population proportion of trusting people in Chicago is higher for the older group?
