Parameter usually takes the form of Greek letter. It is not a percentage. If you estimate it or you know the model, it's an actual number. It normally represents the effect on the change of one unit of one particularvariable.
what do you mean when the population is uncertain? In any statistical studies, defining study and target population is an earlier step than coming up with the model where you introduce parameters.

Em....I have no idea why your text book has question like that.
48% can be interpret as 0.48 which can be a parameter.
For example, a model Y = b1 X1 + b2 X2 + R,
where b1 denotes beta subscript 1, a parameter
X1 denotes X subscript 1
in this case, b1, which is a parameter, can take the value of 0.48 which represents 1 unit of change in X1 affect the outcome by 0.48.
