Two professors at a local college developed a new teaching curriculum designed to increase students' grades in math classes. In a typical developmental math course, 53% of the students complete the course with a letter grade of A, B, or C. In the experimental course, of the 14 students enrolled, 11 completed the course with a letter grade of A, B, or C. Is the experimental course effective at the alpha equals 0.01 level of significance? Complete parts (a) through (g).
