Question

The critical values are r= (Round to three decimal places as needed. Use a comma to separate answers as needed.)

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 = 0.01. 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? 7.2 118 view a table ofc 7.7 205 9.6 239 9.3 198 8.7 197 8.1 182 Overhead Width Weight lick al Ivalues for the correlation coefficient Construct a scatterplot.

The critical values are r= (Round to three decimal places as needed. Use a comma to separate answers as needed.)

Explanation / Answer

Here degree of freedom = 6-2 = 4 and level of significance is 0.01, so critical values from Correlation Coefficient table would be

0.971
