Part B - Grapning experimental data
There are many reports that the number of chirps per minute that a cricket produces is correlated with the ambient temperature. Your
class decides to test this hypothesis by collecting several males from two species of crickets: the snowy tree cricket (Oecanthus fultoni)
and the common field cricket (Gryllus pennsylvanicus). In the laboratory, you measure the chirp rate of each cricket at four different
temperatures. The data are shown in the table below.
