Part 1

Listed below are the overhead widths​ (cm) of seals measured from photographs and weights​ (kg) of the seals. Find the regression​ equation, letting the overhead width be the predictor​ (x) variable. Find the best predicted weight of a seal if the overhead width measured from a photograph is

1.7

​cm, using the regression equation. Can the prediction be​ correct? If​ not, what is​ wrong? Use a significance level of

0.05.

Overhead Width​ (cm)	7.1	7.4	9.7	9.4	8.8	8.3
Weight​ (kg)	137	181	276	236	232	216
