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 7.1 7.8 9.8 9.3 8.7 8.3   Weight 113 211 246 198 201 190   The linear correlation coefficient is r=enter your response here. ​(Round to three decimal places as​ needed.)   The critical values are r=enter your response here. ​(Round to three decimal places as needed. Use a comma to separate answers as​ needed.)
