21. Ready for College? The ACT is a college entrance exam. In NW addition to administering this exam, researchers at ACT gauge high school students' readiness for college-level sub jects. For example, the mean ACT score of all students who took the exam in 2007 was 21.2, with a standard deviation of 4.9. ACT recommends that students who plan to attend col- lege take a minimum set of core mathematics courses. This core is 1 year of credit each in Algebra I. Algebra II, and Geometry. A random sample of 200 students who completed at least this core set of mathematics courses resulted in a mean score of 21.9 on the 2007 ACT. (a) State the appropriate null and alternative hypotheses to assess whether students score better on the ACT when they take the core mathematics curriculum. (b) Use the classical or P-value approach at the = 0.05 level of significance to test the hypothesis in part (a). (c) Write a conclusion based on your results to part (b).
