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, 58?% of the students complete the course with a letter grade of?A, B, or C. In the experimental?course, of the 14 students?enrolled, 12 completed the course with a letter grade of?A, B, or C. Is the experimental course effective at the ?=0.025 level of?significance? Complete parts ?(a) through?(g).

(a) State the appropriate null and alternative hypotheses. H0: p = 0.58 versus H1: p > 0.58 (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 - p0) = 3.4
