  • Pencil And Paper

    i gave the pencil and paper exam on the 26th. anybody out there was able to crack the graph question on F(x) cumulative dist and x. i chose the answer 1.25 for E(x). i have no clue on that one.

    I think you had to take the slope of Fx because it was a continous function.Take the derivative afterward to see that it is a uniform distribution .

      but does anybody know the right answer. i remember for sure that two answer choices were less than 1, the third was 1.25 and the fourth was 2.5.
