Crickets make a chirping noise by sliding their wings rapidly over each other. Perhaps you have noticed that the number of chirps seems to increase with the temperature. The given data list the temperature (in degrees Fahrenheit) and the number of chirps per second for the striped ground cricket. Are temperature and number of chirps per second associated at the a = 0.05 level of significance? Temperature (F) Chirps per Second Temperature (F) Chirps per Second 88.6 20.0 71.6 16.0 93.3 19.8 84.3 18.4 80.6 17.1 75.2 15.5 69.7 14.7 82.0 17.1 69.4 15.4 83.3 16.2 79.6 15.0 82.6 17.2 80.6 16.0 83.5 17.0 76.3 14.4 Source: George W.
