I am having trouble solving this problem.  Can you please provide me with some help.  Thank you.  I appreciate it. Peter D. Hart Research Associates conducted a survey of randomly selected U.S. registered votes to explore public opinion on federal funding for stem-cell research.  The survey found that 56% of college-educated voters and 48% of voters without a college degree supported such funding.  If the samples included 366 college-educated voters and 466 voters without a college degree, can these sample results be used to reject a "no difference in the population proportions" null hypothesis at the 5% significance level?

Types of Bias

Statistics is the study of data collection, organization, analysis, interpretation, and presentation. Statistical bias is a characteristic of a statistical technique or its findings in which the expected value deviates from the actual root quantitative parameter being estimated. According to the actual definition of bias, it refers to the tendency of a statistic to overestimate or underestimate a parameter.
