5. A college entrance exam company determined that a score of 22 on the mathematics portion of the exam suggests that astudent is ready for college-level mathematics. To achieve this

goal, the company recommends that students take a corecurriculum of math courses in high school. Suppose a random sample of 150 students wha completed this core set ofcourses results in a mean math score of 22.3 on the college entrance exam with a standard deviation of 3.8. Do theseresults suggest that students who complete the córe curriculum are ready for college-level mathematics? That is, are theyscoring above 22 on the math portion of the exam?
