| 1 | 12 |
| 1 | 13 |
| 2 | 11 |
| 2 | 11 |
| 3 | 10 |
| 3 | 9 |
| 4 | 7 |
| 5 | 6 |
(a) Using regression to find a linear equation for P(n). Round to 2 decimal places. P(n)P(n) =
(b) How many cups of coffee should he drink so that no one will complain about his attitude? Round to one decimal place.
