Question

if var(x)=8.25,var(y)= 33.96 and cover (x,y)=10.2,then the correlation coefficient is​

Answer 1

Answer:

0.61

Step-by-step explanation:

Given If var(x)=8.25,var(y)= 33.96 and cover (x,y)=10.2,then the correlation coefficient is

Now it is given that

   var(x) = 8.25,var(y) = 33.96 and cover(x,y) = 10.2

   We know that

        correlation coefficient is given by

       r xy = cover(x,y) / √var(x).var(y)

             =  10.2 / √8.25 x 33.96

             = 10.2 / √280.17

            = 10.2 /16.738

           = 0.609 or 0.61

So  the correlation coefficient is​ 0.61
