उत्तर
Statement 2 is true and statement 1 is false.
Explanation:
Statement 1 is false because the strength of a linear relationship is measured by correlation (r), not regression. Statement 2 is true because the regression coefficient is the slope and shows the average change in one variable for a 1-unit change in the other.
