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, 49% of the students complete the course with a letter grade of A, B, or C. In the experimental course, of the 17 students enrolled, 12 completed the course with a letter grade of A, B, or C. Is the experimental course effective at the a = 0.05 level of significance? Complete parts (a) through (g). (a) State the appropriate null and alternative hypotheses. Ho: P = 0.49 versus H: p > 0.49 (Type integers or decimals. Do not round.) (b) Verify that the normal model may not be used to estimate the P-value. Because npo (1-Po) =UI < 10, the normal model may not be used to approximate the P-value. %3D (Round to one decimal place as needed.)
