There are two telephone booths at a train station. Three passengers getting off the train rush to these booths to make a call. All three calls will be of exponentially distributed length, and have the same expected (mean) length. Passengers A and B rush into the booths. The instant either A or B vacates a booth, C will start C’s call. What is the probaility C will be the last of the three to complete the call.

The Coaster commuter train runs crowded trains (200 passengers per train-car) during peak rush-hour commute times, but the there are only 10 passengers per train-car during off-peak hours. A manager of the Coaster says that the cost of running a car for one trip is $50 regardless of the number of passengers onboard: Therefore, the manager says the per passenger cost is $0.25 during peak hours and $5 per passenger in off-peak hours. This implies the Coaster should discourage off-peak...

An train station has determined that the relationship between the number of passengers on a train and the total weight of luggage stored in the baggage compartment

An train station has determined that the relationship between the number of passengers on a train and the total weight of luggage stored in the baggage compartment can be estimated by the least squares regression equation ?=188+25?y=188+25x. Predict the weight of luggage for a flight with 33 passengers.Answer: pounds

Researchers at two universities found that airlines are doing a better job of getting passengers to their destinations on time. Company A and Company B Airlines were among the leaders in on-time arrivals with both having 88% of their flights arriving on time. But for the 12% of flights that were delayed, how many minutes were these flights late? Sample data showing the number of minutes that delayed flights were late are shown below for both airlines. Use Excel to...
