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, 55% 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 = 0.1 level of significance? Complete parts (a) through (g). Is there sufficient evidence to support the research that the experimental course is effective? O A. No, reject the null hypothesis because the P-value is less than a. There is insufficient evidence to conclude that the experimental course is effective. O B. Yes, reject the null hypothesis because the P-value is less than a. There is sufficient evidence to conclude that the experimental course is effective. C. No, do not reject the null hypothesis because the P-value is greater than a. There is insufficient evidence to conclude that the experimental course is effective. D. Yes, do not reject the null hypothesis because the P-value is greater than a. There is sufficient evidence to conclude that the experimental course is effective. (e) Suppose the course is taught with 45 students and 33 complete the course with a letter grade of A, B, or C. Verify whether the normal model may now be used to estimate the P-value. Because npo (1- Po) = V 10, the sample size is 5% of the population size, and the sample the normal model V be used to approximate the P-value. (Round to one decimal place as needed.)
