3. In a Harris poll of 2036 adults, 40% said that they prefer to get their news online. Construct a 95%
confidence interval estimate of the percentage of adults who say that they prefer to get their news
online. Can we safely say that fewer than 50% of adults prefer to get their news online?
4. The LA times printed the headline "Most California Voters Support Legalizing Recreational Marijuana."
That headline was based on a survey of 1879 Californians, with 1090 of them supporting Proposition 64
(which passed during the November 2016 election and opened up the state for legal cannabis sales
starting in 2018). Use the survey results to construct a 95% confidence interval estimate for the
percentage of Californians who support legalization of recreational marijuana. Is the claim in the headline
supported by the poll findings?
