Moderate# Finding the LSRL from a Computer Output: Height and Wingspan

APSTAT-6RLKVY

NBA scouts are always interested in the relationship between the height of NBA players and their respective wingspans. An NBA scout randomly selects $20$ players and measures their heights and wingspans. Below is the computer regression analysis of height and wingspan.

Dependent variable: Wingspan

$R^2 = 0.787$

$S = 2.23$

Degrees of Freedom = $18$

Variable | Coefficient | SE(Coeff) | t-ratio | P-value |
---|---|---|---|---|

Constant | -2.273 | 0.39 | -5.83 | <0.0001 |

Height | 1.084 | 0.24 | 4.52 | <0.0001 |

Write the equation for the least squares regression line.
