Struggling with data

If y is the dependent variable and x is the independent variable. And if the sum of
the cross product of the deviations is E(x – a) (y- y)= -41, and also
if 3.15 and 2.49 are the standard deviations for the independent and dependent
variables, respectively, and we have a sample size of 14, what is the correlation
coefficient between x and y?
