Given below are two statements:
Statement I : In the simple linear regression model with an intercept, the regression slope when multiplied by the explanatory variable X will give the predicted Y.
Statement II : In the simple linear regression model, the regression slope indicates by how many units Y increases, given a one-unit increase in X.
