Conduct a test at the a = 0.05 level of significance by determining (a) the null and alternative hypotheses, (b) the test statistic, and (c) the P-value. Assume the samples were obtained independently from a large population using simple random sampling. Test whether p, >P2. The sample data are x, = 129, n, = 259, x2 =142, and n, = 302. (a) Choose the correct null and alternative hypotheses below. O A. Ho: P1 = 0 versus H: P1 =0 O B. Ho: P1 = P2 versus H1: P1 P2 (b) Determine the test statistic. Zo = (Round to two decimal places as needed.)

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.
