6. the median-median line for a dataset is y=1.133x+0.489 the least-squares regression line for the same dataset is y=1.068x+0.731. which regression equation better predicts the y-value for the point (50, 60) a. the median-median line regression line is a better prediction. b. the least squares regression line is a better prediction. c. the models predict the same value d. the models predict different values that are equally inaccurate (1 point)

The correct option is A. The median-median line regression line is a better prediction.

Step-by-step explanation:

The given median-median line for a dataset is

The least-squares regression line for the same dataset is

The given point is (50,60).

Substitute x=50 in each given equation.

Since the value of median-median line at x=50 is near to 60 than the value of least-squares regression at x=50.

The median-median line regression line is a better prediction. Therefore the correct option is A.
