10.1.23 Question Help ▼ sted 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 ear correlation coefficient r, and find the critical values ofr using a = 0.01. Is there sufficient evidence to conclude that there is a linear correlation between overhead dths of seals from photographs and the weights of the seals? 9.7 9.3 8.8 8.3 Overhead Width Weight 7.2 7.7 118 169 245 199 201 188

The linear correlation coefficient is r= 0.943 (Round to three decimal places as needed.) The critical values are r= -0.811,0.811. (Round to three decimal places as needed. Use a comma to separate answers as needed.) Because the absolute value of the linear correlation coefficient is greater than the positive critical value, there is not sufficient evidence to support the claim that there is a linear correlation between overhead widths of seals from photographs and the weights of the seals for a significance level of a = 0.05.
