Listed below are the overhead widths​ (in cm) of seals measured from photographs and the weights​ (in kg) of the seals. Construct a​ scatterplot, find the value of the linear correlation coefficient​ r, and find the critical values of r using

α=0.05.

Is there sufficient evidence to conclude that there is a linear correlation between overhead widths of seals from photographs and the weights of the​ seals?

Overhead Width    Weight
7.1    114
7.5    155
9.8    249
9.3    197
8.8    200
8.1    182

The linear correlation coefficient is r=

The critical values are r=
