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 18 students enrolled, 12 completed the course with a letter grade of A, B, or C. Is the experimental course effective at the alpha equals 0.025 level of significance? Complete parts (a) through (g). Question content area bottom Part 1 (a) State the appropriate null and alternative hypotheses. Upper H 0: p equals 0.53 versus Upper H 1: p greater than 0.53 (Type integers or decimals. Do not round.) Part 2 (b) Verify that the normal model may not be used to estimate the P-value. Because np 0 left parenthesis 1 minus p 0 right parenthesisequals enter your response here less than not equals greater than equals 10, the normal model may may not be used to approximate the P-value. (Round to one decimal place as needed.)
