This question: 1 point(s) possible A college entrance exam company determined that a score of 22 on the mathematics portion of the exam suggests that a student is ready for college level mathematics. 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 22 7 on the college entrance exam with a standard deviation of 3.3. Do these results suggest that students who complete the core curriculum are ready for college-level mathematics? That is, are they scoring above 22 on the mathematics portion of the exam?
