Rhode Island legalized medical marijuana in 2006. In 2014, a poll was conducted among 400 college-age Rhode Island residents (1) and it was found that 100 supported the legalization of recreational marijuana. And among 500 college-age Massachusetts residents (2) it was found that 150 supported the legalization of recreational marijuana. Find a 99% confidence interval for the true difference in proportion between college-age Massachusetts residents who support the legalization and the proportion of college-age Rhode Island residents who support the legalization of recreational marijuana. The standard error is= 0.0401 0.0217 0.0298 0.0204
