If y is the dependent variable and @ is the independent variable. And if the sum of the cross product of the deviations is Ex - x (y - y )-62, and also if 27.92 and 33.29 are the variances for the independent and dependent variables, respectively, and we have a sample size of 18, what is the correlation coefficient between T and y? Note: 1- Round intermediate numbers to 4 decimal places. 2- Round your final answer to 2 decimal places
