Question
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=0.01.
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?

The linear correlation coefficient is
r=__________
​(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, equal to)
 
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
α=0.05.
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 a = 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?
