Medicare Overbilling Assignment_1
1MEDICARE OVERBILLINGAnswer 1Let X be the number of invoices that are overcharged. Let Y be the number of invoices that are underchargedSample size (n) = 200Probability of being overcharged = 0.06Probability of being undercharged = 0.01Thus, we can say that X ~ Bin (200, 0.06) and Y ~ Bin (200, 0.01)Therefore, P (X ≥ 15) = 1 – P (X < 15) = 1 – P (X ≤ 14) = 1 – BINOMDIST (14, 200, 0.06, TRUE) = 1 –0.778 = 0.222The probabilities are obtained from Excel.Thus, the probability that at least 15 invoices are overcharged is 0.222The probability that there will be no undercharge to the customer is given by the followingprobability:P (Y = 0) = BINOMDIST (0, 200, 0.01, FALSE) = 0.134
