Global Warming by Political Party Does belief in global warming differ by political party? When the question "Is there solid evidence of global warming?" was asked, the sample proportion answering "Yes" was 79% among Democrats and 38% among Republicans. A bootstrap distribution for the difference in proportions (PD - PR) is shown (assuming samples of size 1000 from each party). Give a 95% CI for the difference in proportions using both the 95% rule and the percentile method.
