Sixteen individuals are scheduled to take a driving test at a particular DMV office on a certain day, nine of whom will be taking the test for the first time. Suppose that six of these individuals are randomly assigned to a particular examiner, and let X be the number among the six who are taking the test for the first time. (a) What kind of a distribution does X have (name and values of all parameters)? 9 O b(x; 6, 9 O h(x; 6, 16 Oh(x; 6, 9, 16) Ob(x; 6, 9, 16) O nb(x; 6, L 16 onb(x; 6, 9, 16) (b) Compute P(X = 2), PCX < 2), and P(x > 2). (Round your answers to four decimal places.) P(X = 2) = 1573 P(X 2) = 8794 X P(X > 2) = (c) Calculate the mean value and standard deviation of X. (Round your answers to three decimal places.) individuals mean standard deviation individuals
