Answer:
The correlation between two variables, let's say A and B, is given by:
In our case, we know that:
y = 2*x
And:
r(X, Z) = 0.45
Then:
Now we want to find:
r(Y, Z)
Let's start with r(X, Z)
We know that:
X = Y/2
Then we can replace that in the correlation equation:
And in the third part, we have r(Y,Z), then:
The correlation of z with y is 0.45
