Each time a modem transmits one bit, the receiving modem analyzes the signal arrives and decides whether the transmitted bit is 0 or 1. It makes an error with probability p, independent of whether any other bit is received correctly. a) If the transmission continues until first error, what is the distribution of random variable X, the number of bits transmitted? b) If p = 0.1, what is probability that X = 10? c) what is probability that X > 5? d) If modem transmits 30bits, what is the distribution of random variable Y, the number of error? e) If p = 0.15, what is probability that Y< 3, f) if the transmission continues until third error ,what is the distribution of random variable Z,    the number of bits transmitted?   g) If p = 0.2, what is probability that Z = 5? h) what is probability that Z > 5 ?

Each student arrives in office hours one by one, independently of each other, at a steady rate. On average, three students come to a two-hour office hour time block. Let S be the number of students to arrive in a two-hour office hour time block. What is the distribution of S? What is its parameter? Group of answer choices S ∼ Geo(1/3) S∼Pois(3) S∼Bin(2,1/3) S-Pois(1.5) What is the probability that S = 4? What is the probability that S ≤...

1. On one approach of an intersection with fixed time traffic signal, vehicles arrival rate is 600 vehicles per hour. The effective green time for this approach is 30 seconds, the saturation flow of this approach is 1800 vehicles per hour and the cycle time of the intersection is 80 seconds. a. Evaluate the performance of the signal design i.e. will all vehicles clear during the green time? b. Recommend the changes to the green time for this approach to...

Dean Halverson recently read that full-time college students study 20 hours each week. She decides to do a study at her university to see if there is evidence to show that this is not true at her university. A random sample of 32 students were asked to keep a diary of their activities over a period of several weeks. It was found that the average number of hours that the 32 students studied each week was 19.1 hours. The sample...

5. At each time period, a physical particle can be at one of three locations: A, B, or C. It is never at the same location for two successive time periods and moves to any of the other two locations with probability 1/2. (a) Set up a stochastic matrix corresponding to this Markov process. Is the matrix regular? (Just yes / no answer is not acceptable—show all steps of your reasoning.) (b) Formulate a system of linear equations for finding...
