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, 56% of the students complete the course with a letter grade of A, B, or C. In the experimental course, of the 14 students enrolled, 11 completed the course with a letter grade of A, B, or C. Is the experimental course effective at the a=0.01 level of significance?

**Text Transcription for Educational Website:**

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 14 students enrolled, 11 completed the course with a letter grade of A, B, or C. Is the experimental course effective at the α = 0.01 level of significance? Complete parts (a) through (g).

(a) State the appropriate null and alternative hypotheses.

H₀ [dropdown] versus H₁ [dropdown]

(Type integers or decimals. Do not round.)

**Explanation:**

In this exercise, you are tasked with determining the effectiveness of an experimental teaching curriculum in improving math grades compared to a typical course. A statistical hypothesis test at a 0.01 level of significance will help in making this determination. The null hypothesis (H₀) typically represents no effect or no difference, while the alternative hypothesis (H₁) indicates a significant effect or difference.
