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, 57% of the students complete the course with a letter grade of A, B, or C. In the experimental course, of the 16 students enrolled, 12 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). 0.57 versus H,: p > 0.57 Ho: P (Type integers or decimals. Do not round.) (b) Verify that the normal model may not be used to estimate the P-value. Because npo (1-pPo) =O 10, the normal model V be used to approximate the P-value. (Round to one decimal place as needed.)

Follow-up Question
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, 57% of the students
complete the course with a letter grade of A, B, or C. In the experimental course, of the 16 students enrolled, 12 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).
Because npo (1 - Po) = 3.9
< 10, the normal model may not be used to approximate the P-value.
(Round to one decimal place as needed.)
(c) Explain why this is a binomial experiment.
There is a
number of trials with
V The trials
independent and the probability of success is fixed at for each trial.
(Type an integer or a decimal. Do not round.)
