Chapter 15.4, Problem 4P

At a math center in a class, there is a bag filled with 40 red blocks and 10 blue blocks. Each child in the class of 25 will do the following activity at the math center: Randomly pick 10 blocks out of the bag without looking, and write on one sticky note the number of red blocks and the number of blue blocks picked.
a. Describe a good way to display the data for the whole class. Your proposed display should be a realistic and practical way to show every child’s piece of data (in a class of 25).
b. Sketch a graph that could be the graph you proposed in part (a). Briefly describe the characteristics you expect the graph to have.
c. Write at least four questions about your hypothetical graph in part (b) that the teacher could ask the children. Include at least one question at each of the three levels discussed in Section 15.2 (Read the data, Read between the data, and Read beyond the data). Label each question with its level. Answer your questions.
