NettetSo, our regression equation would be: y= 16.891 x – 355.32. This is the same as that done by method 1 (scatter chart with a trendline). Now, if we wish to predict average medical expenses when age is 72: So y= 16.891 * 72 -355.32 = 860.832. So this way, we can predict values of y for any other values of x.
