Question
**Question 7** If the LSRL relating the independent variable \(x\) and the dependent variable \(y\) for a given problem is \(\hat{y} = 2x + 5\), then an increase of 1 unit in \(x\) is associated with an increase of how many units in \(y\)? a) 7 b) 0 c) 2 d) 5 e) 1 **Explanation:** The equation \(\hat{y} = 2x + 5\) represents the Least Squares Regression Line (LSRL). In this equation, the slope is 2, indicating that for every 1 unit increase in \(x\), \(y\) increases by 2 units.
