5. The weight, \(w\) grams, and the length, \(l \mathrm {~mm}\), of 10 randomly selected newborn turtles are given in the table below.
| \(l\) | 49.0 | 52.0 | 53.0 | 54.5 | 54.1 | 53.4 | 50.0 | 51.6 | 49.5 | 51.2 |
| \(w\) | 29 | 32 | 34 | 39 | 38 | 35 | 30 | 31 | 29 | 30 |
$$\text { (You may use } \mathrm { S } _ { l l } = 33.381 \quad \mathrm {~S} _ { w l } = 59.99 \quad \mathrm {~S} _ { w w } = 120.1 \text { ) }$$
- Find the equation of the regression line of \(w\) on \(l\) in the form \(w = a + b l\).
- Use your regression line to estimate the weight of a newborn turtle of length 60 mm .
- Comment on the reliability of your estimate giving a reason for your answer.
