APFIVE In a study relating the number of close friends $$x$$ to the number of evening Facebook checks $$y$$, the estimated regression equation is given as $$\hat{y} = -1.73 + 0.5492*x$$. Which of the following is true regarding the slope of the regression line?
Regression Equation: $$\hat{y} = -1.73 + 0.5492*x$$
For each additional evening Facebook check, the average number of close friends increases by approximately 0.5492.
For each additional close friend, the average number of evening Facebook checks increases by approximately 0.5492.
The slope value suggests that the relationship between the studied variables is non-linear.
The slope indicates that when there are zero close friends, the predicted number of Facebook checks is 0.5492.
