Let YY represent the profit (or loss) for a certain company XX
years after 1965. Based on the data shown below, a statistician
calculates a linear model Y=−2.09X+22.14Y=-2.09X+22.14.
| x | y |
|---|---|
| 1 | 20.15 |
| 2 | 17.98 |
| 3 | 16.21 |
| 4 | 12.94 |
| 5 | 11.77 |
| 6 | 9.9 |
Use the model to estimate the profit in `1967
y =
For 1967:
x = 1967 - 1965 = 2
Hence,
Estimated profit in 1967 = -2.09 * 2 + 22.14 = 17.96
