Problem 27SE

Refer to Exercise 26.

a. Find μX.

b. Find c. Find Cov(X, Y).

d. Find ρX,Y.

Step-by-Step Solution:

Step 1 of 4 </p>

Given, the amount of copper is X and the amount of nickel is Y.

We assume that X and Y are the joint probability density function.

Our goal is to find :

a). Find b). Find .

c). Find Cov(X,Y)

d). Find .

a).

Now we have to find .

The mean of x is  We are taking the limits 0 to 1.

We integrated then we get.   So  We integrated and applied the limits.          Therefore mean of X is 1.2857

Step 2 of 4 </p>

b).

Now we have to find .

Here is We calculated value.

So    We substituted the value in the above equation.  Therefore Step 3 of 4

Step 4 of 4
