Problem 3. In the setting of Problem 1, what is the expected value and the variance of the first day when the stock price goes up? What is the MGF of this day? What is the probability that this day happens on the sixth day? Problem 1. An investment analyst found that a certain stock price goes up or down a point every day with probabilities 0.75 and 0.25, respectively. Daily fluctuations are independent. Find the probability that after four...

Let X be a random variable with cdf FX (x:0), expected value EIX-μ and variance VlX- σ2. Let X1,X2, , Xn be an id sample drawn according to FX(x,8) where Fx (x,8) =万 for all x E (0,0). Let max(X1, X2, , X.) be an estimator of θ, suggested from pure common sense. Remember that if Y = max(X1, X2, , Xn). Then it can be shown that the cdf Fy () of Y is given by Fr(u) (Fx()" where...
