Your brother Jacob, a first-year student in a statistics class, is given the information in the table below and asked to calculate the expected value of a discrete random variable x. When Jacob comes home in the evening, he is very upset because he cannot complete the task. Since you have taken this class before, you decide to help Jacob without actually completing the assignment for him. Which of the following statements regarding the expected value of a discrete random variable x is correct? X P(x) 12 0.1 13 0.2 14 0.4 15 0.1 16 0.05 17 0.15 It is the outcome that is most likely to occur. O It is computed as a weighted average of the possible outcome of that random variable, where the weights are the probabilities of that outcome. O It can be found by determining the 50% value in the cumulative density function. O It equals the sample median
