Given are five observations collected in a regression study on two variables.
xi |
2 | 6 | 9 | 13 | 20 |
---|---|---|---|---|---|
yi |
7 | 18 | 8 | 26 | 21 |
(a)
Develop the estimated regression equation for these data.
ŷ =
Use the estimated regression equation to predict the value of y when
x = 20.
The statistical software output for this problem is :
(a)
y hat = 8 + 0.8 x
Predicted value = 8 + 0.8 * 20 = 24
