ENEE 324 ASSIGNMENT 13 Due Thu 10/22 Let X be an exponential random variable with λ = 4. (i) (2 pts.) Give a formula for E [ X n ], where n is a positive integer. (ii) (4 pts.) Determine E [( X - 2) 4 ]. (iii) (5 pts.) Determine E [ Y ], where Y = max { e 2 X ,e 2 } . (iv) (5 pts.) Determine E [ d X e ]. ( You may use the formula for the mean of a geometric pmf
