A poll was conducted to investigate opinions about global warming. The respondents who answered yes when asked if there solid evidence that the earth is getting global warming. The results are given in the accompanying data table. Use a 0.05 significance level to test the claim that the sex of the respondent is independent of the choice for the cause of global warming. Do men and women appear to agree, or is there a substantial difference?
