ologists have observed that the chirping rate of crickets of a certain species appears to be related to temperature. The table shows the chirping rates for various temperatures. a) Find and graph the regression line. Temperature (F) Chirping Rate (chirps/min) y= 50 20 55 46 60 79 b) Use the linear regression to estimate the chirping rate at 100F 65 91 70 113 75 140 80 173 85 198 90 211
