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 (-1.25). A decrease in the student-teacher ratio by 2 will: O result in a test score of 698.9 O reduce test scores by 2.5 on average O reduce test scores by 2.28 on average O increase test scores by 2.5 on average
