The null hypothesis (H0) is that the true proportion of the population in favor of the new local policy is 40%, or p = 0.40. The alternative hypothesis (H1) is that the true proportion is not equal to 40%, or p ≠0.40. Show more…

A research center claims that at least 40% of U.S. adults think that the Census count is accurate. To test the claim, they survey a random sample of 600 U.S. adults, of whom 35% say that the Census count is accurate. At a significance level of alpha = .02, is there enough evidence to reject the center's claim?
