I need help with this problem and explanation to this problem.

### Mean Distances and Periods of Planets from the Sun

A graphing calculator is recommended.

The table below shows the mean (average) distances \( d \) of the planets from the sun (taking the unit of measurement to be the distance from the earth to the sun) and their periods \( T \) (time of revolution in years).

| Planet  | \( d \)   | \( T \)     |
|---------|-----------|-------------|
| Mercury | 0.387     | 0.241       |
| Venus   | 0.723     | 0.615       |
| Earth   | 1.000     | 1.000       |
| Mars    | 1.523     | 1.881       |
| Jupiter | 5.203     | 11.861      |
| Saturn  | 9.541     | 29.457      |
| Uranus  | 19.190    | 84.008      |
| Neptune | 30.086    | 164.784     |

#### Exercise

**(a)** Fit a power model to the data. Use \( n = \frac{3}{2} \) (Round your values to one decimal place).

\[ T(d) = \_\_\_\_\_ \]

**(b)** Kepler's Third Law of Planetary Motion states that "The square of the period of revolution of a planet is proportional to the cube of its mean distance from the sun."

Does your model corroborate Kepler's Third Law?
- Yes
- No
