Materials: Box of matches Marker pen Results: Sample Number 1 2 3 4 5 Marked matches pulled from sample of 20 10*20 = 200 200/6 = 33 10*20 = 200 200/6 = 33 10*20 = 200 200/6 = 33 10*20 = 200 200 /4 = 50 10*20 = 200 200/5 = 40 Sample Num! ber 1 2 3 4 5 Estimated Population 33 33 33 50 40 Estimated...
