Scientists researching crickets have observed that the rate at which a certain species chirps may be related to their surrounding temperature. The table below contains chirping rates of crickets for various temperatures. Temperature (°F) 55 60 65 70 75 80 85 90 Chirping Rate (chirps per minute) 21 46 79 91 123 140 173 198 Find the equation of a linear regression model that is appropriate for this data. a. y = 5x - 252 b. y = -252x + 5 c. y = 5x – 220 d. y = -220x + 5
