Can you predict the temperature based on the number of chirps of a cricket? The data below represent the temperature and number of cricket chirps per 15 seconds. Chirps/15 sec x Temp (oF) y 20 89 16 72 20 93 18 84 17 81 16 75 15 70 17 82 15 69 16 83 15 80 17 83 16 81 17 84 14 76 (a) What does your formula predict is the temperature when crickets are chirping at 18 chirps per 15 seconds? How does your answer compare with the actual temperature when the chirping occurs at 18 chirps per 15 seconds? (b) Do you think your formula would be an accurate model for measuring temperatures near freezing? Explain. (c) Without calculating, what can you say about r?
