help with questions 1 and 2
1. The critical values are r= _____
​(Round to three decimal places as needed. Use a comma to separate answers as​ needed.)
 
2.Because the absolute value of the linear correlation coefficient is
___???greater or less ???__________ than the positive critical​ value, there __??is or 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=0.01
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?
