A Gallup Poll taken in May 2000 asked the question: “In general, do you feel that the laws covering the sale of firearms should be made more strict, less strict, or kept as they are now?” Of the 492 men who responded, 52% said more strict, while 72% of the 538 women who responded said more strict. Assuming these respondents constitute random samples of US men and women, estimate the difference in the proportions of women and men in the population who think these laws should be made more strict with a 98% confidence interval.
