If Y is the dependent variable and æ is the independent variable. And if the sum of the cross product of the deviations is (x – a) (y – 9 )- -40, and also if 10.19 and 6.72 are the variances for the independent and dependent variables, respectively, and we have a sample size of 12, what is the correlation coefficient between x and Y?
