F. A sociologist is interested in the difference in voting rates between women and men. One hundred women and one hundred men are randomly sampled. Of these, seventy percent of the women and sixty-five percent of the men voted in the last election. 1. Construct a 95% confidence interval around the difference in the proportion of women and men in the population who voted in the last election. 2. Interpret this interval. 3. Test the null hypothesis that, in the population, there is no difference in the proportion of women and men who voted in the last election. Use a significance level of .05. 4. What can you conclude about the relationship between the two variables in this example? (That is, is the relationship statistically significant?)
