A CJ researcher is interested in monitoring public opinion about gun permits for handguns. One of the factors being examined is political affiliation. The researcher randomly selects 10 people from each affiliation (conservative, independent, liberal). Respondents are asked "on a scale from 0 to 10, where 0 is not at all and 10 is completely, how important is it that gun permits should be required for people who wish to own a handgun?"
Test the null hypothesis that public opinion about gun permits does not differ by political affiliation (Use an α = .05) in your calculations. (MUST SHOW WORK FOR FULL CREDIT).
