Consider two continuous random variables X and Y with marginal distributions g(x) and )respectively and the joint density function given by: f(x, y) = {, x > 2, 0 < y < 1, elsewhere. Then: O None of these O x and Y are statistically dependent O f(xly)=g(x) Of(yix)#h(y)

The number of dollars a round trip plane ticket costs from North America to Europe is normally distributed with a mean of $1,780 and a standard deviation of $335. What is the probability a randomly selected ticket costs between $775 and $2,785? Enter your answer in decimal form. For example. 75% should be entered as 0.75

6. Let X and Y be continuous random variables with joint density function 24xy if 0 < x < 1,0 < y < 1 – x f (x, y) = 0. otherwise. Calculate E(Y|X = }).
