Question

The y-intercept (b0) represents the _______.

1) Change in estimated average y per unit change in x
2) Variation around the sample regression line
3) Predicted value of y
4) Predicted value of y when x = 0

Answer 1

The y-intercept (b0) represents the predicted value of y when x = 0.

Step-by-step explanation:

The y-intercept (b0) represents the predicted value of y when x = 0. In other words, it is the value of the dependent variable (y) when the independent variable (x) is zero. It can be calculated using the equation of a line, y = mx + b, where b is the y-intercept.
