The student government wants to find out how many student that mean The government lost the number moment once the exact data exact number. So for this, he should take each and every each and every student data. So for this, a pollster interviews Eastern selected at random as the board was. So he should cocoa each and every each and every your students interview. But he takes randomly, so that means here is biased in data collection.
