Explanation / Answer

SAMPLE IS THE SUBSET OF THE POPULATION , BOTH HAVING THE SAME NATURE OF THE ITEM.

WE CAN SAY THAT POPULATION IS LARGE AND SAMPLE IS SMALL

HERE THE POPULATION WILL BE THE 500 OF COMPONENT WHILE THE SAMPLE WILL BE 25 OF THOSE COMPONENTS.

THEREFORE THE CORRECT STATEMENT = the components being tested are the sample and the sample size is 25. All components produced in an hour is the population.

THEREFORE OPTION D IS CORRECT
