Question
14. For each study described below, which statistical test is most appropriate? Be specific. The average salary paid to teachers, expenditures per pupil, and geographical location are three common factors that contribute to the quality of public elementary schools. You want to determine which of these factors is the most influential in predicting school quality in a sample of 250 randomly selected schools. You timed the rate at which participants could solve a puzzle under three conditions of noise: high, medium, and low. In addition, the participants were under the influence of either alcohol, Red Bull, or orange juice. Each participant solved one puzzle. The Association of Community Organizations for Reform Now (ACORN) is examining the role of racial bias in mortgage rejection rates at U.S. financial institutions. ACORN tallies the number of rejections and acceptances separately for white applicants and applicants of color. U.S. News and World Report publishes a list of the "best" U.S. liberal arts colleges. Reed is well known for refusing to play this rankings game. Nevertheless, you are interested in whether West Coast colleges are systematically higher- or lower-ranked than East Coast colleges. Aunt Em and Uncle Henry complain to Dorothy that Kansas had more days with tornado warnings last year than in a typical year. Dorothy believes that her relatives are exaggerating, and that the frequency of tornado warnings last year was fairly typical.
