A zoologist collected wild lizards in the Southwestern United States. Thirty lizards from the genus Phrynosoma were placed on a treadmill and their speed measured. The recorded speed (meters/second) is the fastest time to run a half meter (courtesy of K. Bonine).

(a) Construct a frequency distribution using the class intervals 0.45-0.90, 0.90-1.35, and so on, with the endpoint convention that the left endpoint is included and the right endpoint is excluded. Calculate the relative frequencies.
(b) Make a histogram.
