Regression Output: Circumference and Melon Weight

APSTAT-$DF57I

Farmer MacDonald sells his melons at a roadside stand. He hates carrying along his scale for weighing the melons though and wonders if there is a way to predict the weight ($\hat {y}$) of a melon by measuring its circumference ($x$).

Luckily, his son Junior is taking A. P. Statistics and knows just what to do! After weighing (in pounds) and measuring the circumference (in inches) of a random sample of melons, Junior uses a statistical software package to develop the equation of the LSRL. Computer output is shown below.

A

$\hat { y } =0.623+1.02x$

B

$\hat { y } =1.02+0.623x$

C

E

$\hat { y } =2.18+1.63x$
