# Question

One classic application of correlation involves the association between the temperature and the number of times a cricket chirps in a minute. Listed below are the numbers of chirps in 1 min and the corresponding temperatures in °F. Is there sufficient evidence to conclude that there is a linear correlation between the number of chirps in 1 min and the temperature?
