Two professors at a local college developed a new teaching curriculum designed to increase students' grados in math classes. In a typical developmental math course, 51% of the students complete the course with a letter grade of A, B, or C. In the experimental course, of the 19 students enrolled, 12 completed the course with a letter grade of A, 8, or C. Is the experimental course effective at the a=0.1 level of significance? Complete parts (a) through (g) Ho PF 051 versus H, P > 0.51 (Type integers or decimals. Do not round) (b) Verify that the normal model may not be used to estimate the P-vakue Because npo (1 - Po) = 47 < 10, the normal model may not be used to approximate P-value (Round to one decimal place as needed.) (c) Explain why this is a binomial experiment There is a foxed nurnber of trials with two mutually exclusive outcomes The trials are independent and the probabil ity of success is foxed at 0.51 for each trial. (Type an integer or a decimal. Do not round) (d) Detemine the P-value using the binomial probability distribution State your conclusion to the hypothesis test. First determine the P-value.
