Lisa is at a bus stop. The times between successive bus arrivals are independent and identically distributed exponential random variables with mean 3 minutes. While lisa is waiting, Mindy calls to say she will arrive in exactly 3 minutes. Lisa will wait for Mindy and they will ride a bus together. Calculate the probability that Lisa will miss the first and both Lisa and Mindy will catch the second bus.

Solutions

Expert Solution

3minute is the Time interval is taken, and average number of bus arrival in the given time period is 1, so the event (bus arrives) follows Poisson (1).

6.The time of arrivals between two successive cars to a gas station is assumed to have an exponential distribution with mean 8 minutes. A maintenance operation is started on the road. A random sample of 36 arrival times are recorded to determine the effect of maintenance operation, and average time between arrivals is found as 10 minutes. a) Test the hypothesis that the mean arrival time has changed. Use =0.05. b) Discuss what practical conclusions you would draw in part...

Question 4: The times that a cashier spends processing each person’s transaction are independent and identically distributed random variables with a mean of µ and a variance of σ2 . Thus, if Xi is the processing time for each transaction, E(X i) = µ and Var(Xi) = σ2 . Let Y be the total processing time for 100 orders: Y = X1 + X2 + · · · + X100 (a) What is the approximate probability distribution of Y ,...
