Assume a Poisson random variable has a mean of 5 successes over a 120-minute period.


a. Find the mean of the random variable, defined by the time between successes.



b. What is the rate parameter of the appropriate exponential distribution? (Round your answer to 2 decimal places.)



c. Find the probability that the time to success will be more than 50 minutes. (Round intermediate calculations to at least 4 decimal places and final answer to 4 decimal places.)

    The number of automobiles entering a tunnel per 2-minute period follows a Poisson distribution. The mean number of automobiles entering a tunnel per 2-minute period is four. (A) Find the probability that the number of automobiles entering the tunnel during a 2minute period exceeds one. (B) Assume that the tunnel is observed during four 2-minute intervals, thus giving 4 independent observations, X1, X2, X3, X4, on a Poisson random variable. Find the probability that the number of automobiles entering the...
