The common cricket can be used as a crude thermometer. The colder the temperature, theslower the rate of chirping. The table below shows the average chirp rate of a cricket atvarious temperatures.Chirp Rate(chirps/second)29Temperature(°F)614205553.877.52.558.81.753.41.6526The least-squares regression line for predicting the temperature from the chirp rate is y =340812 + 10.6698x. Predict the temperature (to the nearest tenth of a degree) if the chirp rate is 2.5 chirps p
