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, 56% of the students complete the course with a letter grade of A, B or C. In the experimental course, of the 15 students enrolled, 11 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. H: p = 0.56 versus H,: p > 0.56 (Type integers or decimals. Do not round) (b) Verify that the normal model may not be used to estimate the P-value Because np (1-P)-3.7
