The independent variable is
The dependent variable is
The regression coefficients,
Draw the table
Therefore, the regression coefficients (the slope m, and the y- intercept n).
The regression equation is
The slope of the regression line is
Since the sign is negative,
Therefore the slope is a negative linear relationship between the percent return and new adults.
