I have this question just because according to the definition of paramter in the textbook, I do think parameter should be a number.But in the exercises.There is always this kind of questions:Is the value 48% a parameter of a statistic.
What I mean population is uncertain is because sometimes you don't know the number of population.For example, You may don't how many people will be interested in voting.So what 's parameter when you don't know the definite number of population?Is that the same number with statistic?
