Determine the equation of the regression line of
the average temperature ( ) x with respect to the
latitude ( ) y , and the correlation coefficient for
both variables. Next, use the regression formula
to estimate the expected average temperature for
a city located at latitude 44 North.
First of all, we should enter the data:
Now, we can already compute the Regression
Coefficient A (as described in the table above):
