Chapter 5, Problem 54E(choose chapter or problem)
In Exercise 5.10, we proved that
\(f\left(y_{1}, y_{2}\right)=\left\{\begin{array}{ll}
1, & 0 \leq y_{1} \leq 2,0 \leq y_{2} \leq 1,2 y_{2} \leq y_{1}, \\
0, & \text { elsewhere }
\end{array}\right.
\)
is a valid joint probability density function for \(Y_{1}\), the amount of pollutant per sample collected above the stack without the cleaning device, and \(Y_{2}\), the amount collected above the stack with the cleaner. Are the amounts of pollutants per sample collected with and without the cleaning device independent?

ANSWER:
Answer:
Step 1 of 1:
We have given the joint probability density function.
Is a valid joint probability density function for the amount of pollutant per sample collected above the stack without the cleaning device, and for the amount collected above the stack with the cleaner.
Are the amounts of pollutants per sample collected with and without the cleaning device independent?
If are continuous random variables with joint density function
and marginal density functions respectively, then
are independent if and only if
