1. Mark 30 small pieces of paper with an A, a B, or a C. Put the pieces of paper in a bag. Trade bags with other students in the class. a. Generate a sample by choosing a piece of paper from your bag 10 times, replacing the piece of paper each time. Record the number of times you choose each letter. Repeat this process to generate five more samples. b. Use each sample to make an estimate for the number of As and Bs in the bag. Then describe the variation of the six estimates. Make estimates for the numbers of As, Bs, and Cs in the bag based on all the samples. c. Take the pieces of paper out of the bag. How do your estimates compare to the population? Do you think you can make a more accurate estimate? If so, explain how.
