Bill and Kathy, there are no dumb questions. I don't know your boat, but from the pictures it looks like this pump is in the starboard cockpit lazerette. Open that door in the seat pan, just left of the pump, and stick your head in it, looking aft towards the pump. If you can see the pump itself, you should see two hoses attached. One will run from the pump to some sort of overboard exit fitting, and that fitting may (or may not) be near the pump.. You should learn where that exit is, so you can monitor it when you test the pump.
The other hose will likely run forward, and end up in the bilge. No telling how the hose is routed, but a good start would be a plumbing diagram in the owner's manual, if you have one for the boat. One can probably also be found online. However, it may not be the way the factory plumbed it, so just take a look. Follow this second hose until it disappears around a corner or though something like a bulkhead or a cabinet. Then go to the other side of the bulkhead or cabinet wall, and visually reaquire the hose. Follow it visually until it disappears again. Repeat the above steps, until you determine how it is routed to the bilge. At the end of the hose in the bilge, there is likely to be some sort of relatively heavy fitting to weight down the end, and the fitting should have a screen. You don't want the hose getting clogged with small stuff when you need it to pump water.
By all means, test the pump. Take a 2 gallon or larger bucket of water down to the bilge and put the hose into it, then have someone use the handle (which you need to find, or make a new one) to work the pump. Verify that it moves water, and expels that water overboard.
Hope this helps. The process will help you learn about your boat - where things are, etc. You will likely see other hoses, and some wiring, during this exercise. It pays to know where EVERYTHING is.
Edit: Beat me to it.
