Question

Assume that the relationship between test scores and the student-teacher ratio can be modeled as a linear function with an intercept of 698.9 and a slope of (-2.28). An decrease in the student-teacher ratio by 1 will: decrease test scores by 2.28

•on average increase test scores by 2.28 •on average increase test scores by 698.9 •on average result in a test score of 698.9

Answer 1

Explanation:

Yes, based on the provided information, if the relationship between test scores and the student-teacher ratio can be modeled as a linear function with an intercept of 698.9 and a slope of -2.28, then a decrease in the student-teacher ratio by 1 will decrease test scores by 2.28 points. This suggests that as the student-teacher ratio decreases (indicating fewer students per teacher), test scores are expected to decrease by 2.28 points for each unit decrease in the ratio. It reflects a negative correlation between these variables.
