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? Complete parts (a) through (g. (a) State the appropriate null and altem

![**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.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fca98936e-33c7-4402-95ae-aeafe8e3f8b8%2F1e909188-50ba-40e2-8b50-3ff0aeae12d4%2Fyz8xp46_processed.jpeg&w=3840&q=75)
