Explanation of Solution

We have to know which of the sampling method was used in each of the following settings, in order from I to IV. Thus, in I statement, convenience sample or voluntary response sample is used because the first twenty students are conveniently chosen. In II statement, simple random sample is used because every individual has an equal chance of being chosen.
