A survey was done by StatCrunch before the 2012 U.S. national elections. People were asked their political party and how important the immigration issue was to the election: 1 represents the lowest level of importance and 10 the highest level. See the following output. Do a complete analysis using ANOVA with a significance level of 0.05. Do post-hoc tests based on the intervals given. Remember that an interval for a difference that captures 0 shows that there could be no difference. Use the underlining method, listing the parties from the party with the lowest mean on the left to the party with the highest mean on the right, and underline any pairs or groups of three that are not significantly different. Finally, write your conclusions. For the purpose of this exercise, treat the respondents as a random sample of all StatCrunch users.
