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?
Overhead Width | 7.0 | 7.7 | 9.8 | 9.3 | 8.7 | 8.2 |
|
Weight | 108 | 203 | 247 | 198 | 201 | 185 |
Construct a scatterplot below.
The linear correlation coefficient r is __?
(Round to three decimal places as needed.)
The critical values are r=__?
(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/less? than the positive critical value, there is/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 =0.01.
