Suppose that a sample of 4 pairs of data produced a test statistic of r=0.829. A significance level of = 0.05 is to be used. (a) Find the critical values that would be used to test for significant linear correlation. Do not type " \pm " in front of your answer (the \pm is already given in front of the answer box below). Round your answer to 3 places after the decimal point, if necessary. r= (b) Is there significant linear correlation in this case? There is not significant linear correlation. There is significant linear correlation
