Find the linear correlation coefficient, r, then determine whether there is sufficient evidence to support the claim of a linear correlation between the two variables. The linear correlation coefficient is r= (Round to three decimal places as needed.)Table of critical values n or =.05 of = .01 .950 .990 .878 .959 .811 .917 754 .875 .707 .834 .666 .798 .632 .765 .602 .735 12 .576 .708 13 553 .684 14 .532 .661 15 .514 .641 16 .497 .623 17 .482 .606more: To test Ho: p = 0 against H]: p at O. reject Ho if the absolute value of r is greater than the critical value in the table
