- Let f(x, y) = x + y for 0 < x < 1 and 0 < y < 1 The Conditional Variance of Y when X = ; isLet Y > 0 be a continuous random variable representing time from regimen start to bone-marrow transplant. Everyone does not survive long enough to get the transplant. Let X > 0 be a continuous random variable representing time from regimen start to death. We can assume X ⊥ Y and model time to death as X ∼ Exp(rate = θ) and time to transplant as Y ∼ Exp(rate = µ). Where Exp(rate = λ) denotes the exponential distribution with density f(z | λ) = λe−λz for z > 0 and 0 elsewhere - with λ > 0. Find the probability that the patient would die before receiving transplant.Let X ~ U[0,1] and Y = -βln(1-X). What is the distribution of Y? Justify.
- Let random variable X be uniform in the interval (0, 1). Define random variable Y = aX + b where a not 0.Let Y be a random variable with pdf f(y)= (1/18)(y^3−1) for 1<y<3.(a) Calculate P (Y > 2.5).(b) Calculate the variance of Y .Let X be a random variable with a uniform distribution over the interval [-2 , 4]. Determine the standard deviation of X.
- Let the random variable X fit uniformly in the interval (-1,1). Find the distribution of the random variable X².Let X and Y be independent Exp(2) random variables. Define W = X + Y. a) Determine the correlation between X and W. The joint pdf of X and W is: fx,w(x, w) = 1^(2) e^(-1w) I{O(26) Let X b(8,- Var-x) and distribution function.SEE MORE QUESTIONS
