Ill. 10% is the exact SE for the percentage of 1's in the 25 draws. IV. The 9S%-condence interval for the percentage of 1's in the 25 draws is between 30% and 50%. V. If we want the SE for the percentage of 1'5 in the 25 draws to reduce by half, we need to increase the number of draws to 50. _ Which of the following statements is FALSE for sample surveys.
