Question

Two professors at a local college developed a new teaching curriculum designed to increase students' grades in math clas developmental math course, 55% of the students complete the course with a letter grade of A, B, or C. In the experimental enrolled, 14 completed the course with a letter grade of A, B, or C. Is the experimental course effective at the c = 0.01 level parts (a) through (9) (Type integers or decimals. Do not round.) (b) Verify that the normal model may not be used to estimate the P-value. Because np. (1-P) - 10, the normal model be used to approximate the P-value.

Answer 1

mp (1 - P.) = 14 * 0.55 % (1 – 0.55 = 3.465

Hence,

The correct answer in blanks will be:

3.5; <; can not
