Test interviews of two personnel evaluation techniques are available, the first requires a two-hour test interview while the second can be completed in less than an hour. The table below is the output of the regression analysis of the 15 individuals who took both tests: (i) Calculate the sample correlation coefficient between Test 1 and Test 2 (ii) if the correlation of determination between test 1 and test 2 is M. Comment on the value of this correlation determination.
