1. Contin 1. 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 following data list the temperature (in degrees Fahrenheit) and the number of chirps per second for the striped ground cricket.

on a summer evening has probably heard crikckets. Did you know that it is possible to use the cricket as a thermometer? Crickets tend to chirp more frequently as temperatures increase. This representing chirps per second and y is a random variable re i George W. Pierce, a physics professor at Harvard. In the following data, x is a random variable representing temperature (°F) L.1 87.0 734 94.551 818 752 697 820 15.4 69.4 833 79.6 82.6 80.6835 76.3 Complete...
