My Notes OAsk Your Tea 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 (a) What kind of a distribution does X have (name and values of all parameters)? A, b(x; 6, 16 b(x; 6, 9, 16) nb(x: 6,9, 16) h(x; 6,1 o h(x; 6, 9, 16) (b) Compute P(X 4), P(X s 4), and P(X 2 4). (Round your answers to four decimal places.) x-4)-0.3304 P(X S 4)0.8793 P(X 2 4)0.1207 Calculate the mean value and standard deviation of X. (Round your answers to three decimal places) mean standard deviation 0.9922 (c) individuals individuals 3.375 Need Help?

Explanation / Answer

P(X >= 4) = 1 - P(X < 4)

P(X < 4) = P(X <= 4) - P(X = 4) = 0.8793 - 0.3304 = 0.5489

P(X >= 4) = 1 - 0.5489 = 0.4511
