OceanWings Ferry Service currently offers boat services connecting a total of five islands: Palmara, Quinzel, Rockford, Selene, and Triton. In the diagram, circles represent the five islands. Each line connecting two circles is a sea route that represents all the direct boat services currently offered between the two corresponding islands, each of which is called a port for all boat services represented by the route. Boat services are offered in both directions for each sea route in the diagram, and all boat services currently offered by OceanWings are represented in the diagram. The label for each sea route shows the time taken, in hours, for the boat service between the two islands the route connects, followed by the average annual revenue, in USD, generated by all OceanWings boat services between the two islands.
If a direct boat service is not available between a passenger’s origin island and destination island, OceanWings passengers may take a sequence of boat services to arrive at their destination. The total time taken for such a journey is the sum of the travel times of all boat services on the trip.

OceanWings plans to add three new sea routes with service to a sixth island, Umbra: a route with boat services between Selene and Umbra with a travel time of 2.5 hours; a route with boat services between Triton and Umbra with a travel time of 3 hours; and a route with boat services between Palmara and Umbra with a travel time of 2 hours. No other changes would be made to currently available routes. Based on the information provided, for each of the following quantities, select Yes if the quantity would change after the implementation of these new routes. Otherwise, select No.
| Yes | No | |
| Average (arithmetic mean) of travel times across all current and newly implemented sea routes. | ||
| Median of travel times across all current and newly implemented sea routes. | ||
| Range of travel times across all current and newly implemented sea routes. |
