Ten pairs of points yielded a correlation coefficient r of 0.73. If alpha = 0.05, what is the decision that you will make assuming a two-tail test?
A correlation coefficient was computed for n = 20, alpha = 0.05, and r = 0.692. Using the t-test for the correlation coefficient, what is the critical value, assuming a one-tail positive test?
