Assume that a sample of bivariate data yields the correlation coefficient, r, indicated. Use the table on the right for the specified sample size and level of significance to determine whether a linear correlation exists. r=0.81 when n=10 at a = 0.01 Does a linear correlation exist? A linear correlation does not exist. OA linear correlation exists.
