Question

using technology, the slope of the least-squares regression line is
0.10, which means for each additional absence, the gpa will increase by 0.10 points.
0.10, which means for each additional absence, the gpa is predicted to increase by 0.10 points.
−0.10, which means for each additional absence, the gpa will decrease by 0.10 points.
−0.10, which means for each additional absence, the gpa is predicted to decrease by 0.10 points.

Explanation:

En una regresión de mínimos cuadrados, la pendiente indica la relación predictiva entre la variable independiente (ausencias) y la variable dependiente (GPA). Un valor negativo de pendiente significa que a medida que aumenta el número de ausencias, el GPA se predice que disminuya. Además, es importante resaltar que la regresión genera predicciones, no certezas absolutas.

Answer:

−0.10, which means for each additional absence, the GPA is predicted to decrease by 0.10 points.
