Please email us. They will do a sampling experiment to try to determine which bag has equal amounts of the two types of fish. Each group can only sample 10 fish, one at a time with replacement, from each bag. Record the group's findings in a table on the board. Have each group use the interactive pie chart to model the percentage of parmesan and percentage of cheddar in each of their bags.
Groups can either print out their pie graphs or draw rough sketches of the representation.
There should be enough variability in the data that the students do not feel very confident in their predictions, since they only sampled 10 fish. This should raise issues of sample size. Ask students to say why a larger sample size might be more helpful. They will have an opportunity to explore larger samples in the Fish Farm II activity. Angel had the same number of male and female fish in her pond.
