The server administrator collects a sample of 400 inter- arrival times (in seconds) of food ordering requests from the mobile app to its server during lunchtime. The mean inter-arrival times is 0.1563 seconds.


Extracted text: Use the Poisson distribution model as appropriate to answer questions d) and e) d) Calculate the probability that three food order requests will arrive to the server in a particular interval of one second. e) Calculate the probability that three or more food order requests will arrive to the server in a particular interval of one second. f) Using the t-statistic, construct a 95% confidence interval for the mean inter-arrival time of food order request to the server
