The outside temperature can be estimated based on how fast crickets chirp.
At 104 chirps per minute, the temperature is 63 °F.
At 176 chirps per minute, the temperature is 81 °F.
Using this information, you can make a formula that relates chirp rate to temperature. Assume the relationship is linear, that is the points form a straight line when plotted on a graph.
