To achieve this goal, the company recommends that students take a core curriculum of math courses in high school. Suppose a random sample of 200 students who completed this core set of courses results in a mean math score of 21.4 on the college entrance exam with a standard deviation of 4.2. Using a 0.05 level of significance, do these results suggest that students who complete the core curriculum are ready for college-level mathematics?
