correlation between distance and sidereal year statistics homework help

/in /by

The time it takes for a planet to complete its orbit around a particular star is called the​ planet’s sidereal year. The sidereal year of a planet is related to the distance the planet is from the star. The accompanying data show the distances of the planets from a particular star and their sidereal years. Complete parts​ (a) through​ (e).
