For a set of data, x is the explanatory variable. Its mean is
8.2, and its standard deviation is 1.92.
For the same set of data, y is the response variable. Its mean is
13.8, and its standard deviation is 3.03.
The correlation was found to be 0.223.
Select the correct slope and y-intercept for the
least-squares line.
Slope = -0.35
y-intercept = -10.9
Slope = -0.35
y-intercept = 10.9
Slope = 0.35
y-intercept = -10.9
Slope = 0.35
