Crickets and Temperature A classic application of correlation involves the association between the temperature and the number of times a cricket chirp 1 minute. Listed below are the numbers of chirps in 1 min and the corresponding temperatures in based on data from The Song of Insects, by George W. Pierce, Harvard University Press). Is there sufficient evidence to conclude that there is a linear correlation between the number of chirps in 1 min and the temperature?

Chirps in 1 min 882 1188 1104 864 1200 1032 960 900 Temperature 1 F 69.7 93.3 84.3 76.3 88.6 82.6 71.6 79.6
