1. California’s population in a recent year was reported as 37,691,912 by the U.S. Census Bureau. This makes California the most populated state. Find the sample size required for a survey intended to estimate the percentage of adults in California who use the Internet. Assume a confidence level of 95% and a margin of error of 3.5 percentage points.

2. The Los Angeles 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 would legalize the personal use of marijuana. Use the survey results to construct a 95% confidence interval estimate of the percentage of California who support legalization of recreational marijuana. Is the claim in the headline supported by the poll finding?
