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 the planet is related to the distance the planet is from the star. Accompanying data show the distance of the planets from a particular star and their sidereal years. Complete part a through e. x million of miles/ y sidereal year
Planet Distance from the star x Sidereal Year, y
Planet1 36 0.22
Planet2 67 0.64
Planet3 93 1.00
Planet4 142 1.88
Planet5 483 11.9
Planet6 887 29.3
Planet7 1,785 84.0
Planet8 2,797 165.0
Planet9 3.675 248.0
(a) Has been done.
(b) Determine the correlation between distance and sidereal year. The correlation between distance and sidereal year is (......)(Round to three decimal places as needed).
(c) Compute the least square regression line.
(d) Plot the residuals against the distance from the star
Do you think the least squares regression line is good model?
