(a) Find the 90% confidence interval for the mean heart rate reduction for a dose of 2.2 mg.
(b) Find the 90% prediction interval for the heart rate reduction expected for an individual receiving a dose of 2.2 mg.
| x, Drug Dose in mg | 2 | 1.25 | 2.75 | 0.5 | 1.25 | 0.5 | 2.6 | 1.25 | 1.25 | 1.7 |
| y, Heart Rate Reduction | 11 | 14 | 10 | 11 | 10 | 18 | 8 | 13 | 14 | 13 |
