Anyone who has been outdoors on a summer evening has probably heard crickets. Did you know that it is possible to use the cricket as a thermometer? Crickets tend to chirp more frequently as temperatures increase. This phenomenon was studied in detail by George W. Pierce, a physics professor at Harvard. In the following data, x is a random variable representing chirps per second and y is a random variable representing temperature (°F). 16.6 81.4 20.3 14.7 16.8 73.0 20.6 93.5 18.2 86.3 15.5 75.2 17.1 82.0 X y y 89.4 69.7 15.0 79.6 17.2 17.0 83.5 15.4 16.2 83.3 16.0 80.6 14.4 76.3 y 69.4 82.6 n USE SALT Complete parts (a) through (e), given Ex = 251, Ey = 1205.8, Ex² = 4247.04, Ey² = 97,578.86, Exy = 20,322.37, and r 0.8325.
