Peter D. Hart Research Associates conducted a telephone survey among college educated and noncollegeeducated registered voters to explore public opinion on federal funding for stem cell research. The survey reported that 56% of the college educated sample and 48% of the noncollegeeducated sample supported such funding (resultsforamerica.org). If the sample consisted of 336 college educated voters and 466 noncollegeeducated voters, can these sample results be used to reject a “no difference in population proportions” null hypothesis at the 5% significance level?
