Part (a) was answered well although a small minority of candidates insisted on dividing by n (where n was usually 4). Part (b), on the other hand, caused great confusion. Some interpreted F(1.5) as E(1.5X) , others interpolated between P(X =1) and P(X = 2) and a few thought that F(1.5) was zero since X has a discrete distribution.

To leave the discrete probability distribution, press 2nd QUIT. To find the mean (expected value) and standard deviation, press the STAT key, highlight CALC using the arrow keys and then select the 1-VAR STATS option (#1). Then enter L1, L2. Remember L1 is x and L2 is P(x). Press ENTER to view the descriptive statistics.
