Two professors at a local college developed a new teaching currículum designed to increase students' grades in math classes. In a typical developmental math course, 51% of the students complete the course With a letter grade of A, B I the experimental course, of the 18 students enrolled, 13 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- 0.51 versus Hy: P> 0.51 (Type integers or decimals. Do not round.) (b) Verify that the normal model may not be used estimate the P-value. Because npo (1-Po) -4.5 > 10, the normal model may not be used to approximate the P-value. (Round to one decimal place as neoded.) (c) Explain why this is a binomial experiment. are independent and the probability of success is fixed at 0.51 for each trial. There is a fixed number of trials with two mutually exclusive outcomes. (Type an integer or a decimal. Do not round.) The trials (d) Determine the P-value using the binomial probability distribution. State your conclusion to the hypothesis test.
