1 y>0, so the absolute value is silly
2 what is R?
3 when you differentiate it's better to rewrite this as
so you don't need to use the chain rule here.
Product lifetime is Y=5X^0.7 and X has exponential distribution of . Find distribution function and p.d.f. of Y.
My Guess Work:
So far, I know and since the mean is 1.
When I take the derivative of the equation after substituting for x, I get .
Then multiplying the absolute value of this equation by the original equation of , I get
I really have no idea how to get the right answer to this problem.
