Answer:
The correct option is D) reduce test scores by 4.56 for every school district.
Explanation:
Based on the information in the question, the relationship between test scores and the student-teacher ratio can be mathematically written as follows:
x = 698.9 - 2.28y .................... (1)
Where,
x = test scores
y = student-teacher ratio
The a slope of (-2.28) indicates the amount by which x will change whenever there is a change in y.
Therefore, when there is a decrease in the student teacher ratio by 2 (i.e. y = 2), we will have:
Change in x = -2.28 * 2 = -4.56
The negative sign therefore indicate that the test scores will reduce by 4.56 for every school district. Therefore, the correct option is D) reduce test scores by 4.56 for every school district.
