Emergency 911 calls to a small municipality in Idaho come in at the rate of one every two minutes. Assume that the number of 911 calls is a random variable that can be described by the Poisson distribution. (a) What is the expected number of 911 calls in one hour? per hour (b) What is the probability of three 911 calls in five minutes? If required, round your answer to four decimal places. (c) What is the probability of no...

Emergency 911 calls to a small municipality in Idaho come in at a rate of 6.9 calls every hour. Assume that the number of 911 calls is a random variable that can be described by a Poisson distribution. What is the probability of four 911 calls in the next hour? Round your answer three decimal places.

4. The emergency telephone (911) center in a large city receives an average of 210 calls per hour during a typical day. On average, each call requires about 121 seconds fora dispatcher to receive the emergency call, determine the nature and location of the problem, and send the required individuals (police, firefighters, or ambulance) to the scene. The center is currently staffed by 7 dispatchers a shift but must have an adequate number of dispatchers on duty and it has...

93. At a 911 call center, calls come in at an average rate of one call every two minutes. Assume that the time that elapses from one call to the next has the exponential distribution. Where appropriate, round answers to three decimal places (i.e. 0.123) a. On average, how much time occurs between five consecutive calls? Answer minutes b. Find the probability that after a call is received, it takes more than three minutes for the next call to occur....
