possible
A college entrance exam company determined that a score of 21 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 21.3 on the college entrancerexam with a standard deviation of 3.2 Do these
results suggest that students who complete the core curriculum are ready for college-level mathematics? That is, are they
scoring above 21 on the mathematics portion of the exam? Complete parts a) through d) below
