Explanation / Answer

Whenever doing real research, the researcher will rarely know the population parameters. That is because the researcher never works with the real population data, since he/she works on a sample. So option C is correct.

Option B and D are incorrect - You can only determine type 1 and type 2 error based on a predetermined alpha.

Since I've to choose one it seems, C is correct and most compelling.
