Extracted text: 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, 53% of the students complete the course with a letter grade of A, B, or C. In the experimental course, of the 15 students enrolled, 10 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 0.53 versus H1: p 0.53 > (Type integers or decimals. Do not round.) (b) Verify that the normal model may not be used to estimate the P-value.
