Fermilab Butterfly Data

Tom, Fermilab's butterfly expert, has been studying these amazing insects at Fermilab for three years. When Tom goes out butterfly watching, he counts the number he sees per hour of each species. At the end of the summer, he makes a chart with the day on which he saw the maximum number of each species. The number he saw is the "peak count" for that species.

With Tom's data, you can answer a variety of questions. Which question do you want to answer?
