Let X denote the reaction time, in seconds, to a certain stimulus and Y denote the temperature (°F) at which a certain reaction starts to take place. Suppose that two random variables X and Y have the joint density xy Sx² + ² ,0 < x < 1,0 < y < 2, f(x, y) = 3 elsewhere. 0, a. Verify if it is a valid density function. b. Find P[(X, Y) E A], where A = {(x, y) | 0 1 | X = 12). h. Find P(X> ½ | Y = 1). 1. Determine if the random variables are statistically independent.
