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? Compute the test statistic. (Round to 3 decimal places) Find the critical value(s). (Round to 3 decimal places.
