Part 2 of Assignment 2: A questionnaire was distributed to a sample of 30 respondents in each city for City 1, City 2 and City 3, asking respondents' level of support of gun control. Each respondent was asked to circle one of the numbers ranging from 1 to 5, where 1 indicates \"strongly support\"; 2, \"somewhat support\"; 3, \"neither support nor not support\": 4, \"somewhat not support\"; and 5, \"strongly not support\".
