According to a poll, 690 out of 1030 randomly selected adults living in a certain country felt the laws covering the sale of firearms should be more strict. a. What is the value of p, the sample proportion who favor stricter gun laws? b. Check the conditions to determine whether the CLT can be used to find a confidence interval. c. Find a 95% confidence interval for the population proportion who favor stricter gun laws. d. Based on your confidence interval, do a majority of adults in the country favor stricter gun laws? a. The value of p, the sample proportion who favor stricter gun laws, is 0.67 . (Round to two decimal places as needed.) b. Check the conditions to determine whether you can apply the CLT to find a confidence interval. The Random and Independent condition can reasonably be assumed to hold. The Large Sample condition holds. The Big Population condition holds. c. The 95% confidence interval for the population proportion who favor stricter gun laws is (Round to three decimal places as needed.)
