There is a linear relationship between the number of chirps made by the striped ground cricket and the air temperature. A least-squares fit on some data collected by abiologist gives the model y(hat) = 25.2 = 3.3x, 9<x<25, where x is the number of chirps per minute and y(hat) is the estimated temperature in degrees Fahrenheit.What is the estimated increase in temperature that corresponds to an increase of 5 chirps per minute?

(a) 3.3 Fahrenheit
(b) 16.5 Fahrenheit
(c) 25.2 Fahrenheit
(d) 28.5 Fahrenheit
(e) 41.7 Fahrenheit

    Example 19.8. The frequency of chirping of a cricket is thought to be related to temperature. This suggests the possibility that temperature can be estimated from the chirp frequency. Let the following data on the number chirps per second, r by the striped ground cricket and the temperature, y in Fahrenheit is shown below: 20 1620 18 17 16 15 17 15 16 8972 93 8481 75 7082 69 83 Find the normal regression line that approximates the regression of...

  • Biologists have noticed that the chirping rate of crickets of certain species is related to temperature, and the relationship appears to be very nearly linear

    Biologists have noticed that the chirping rate of crickets of certain species is related to temperature, and the relationship appears to be very nearly linear. A cricket produces 113 chirps per minute at 70 degrees Fahrenheit and 173 chirps per minute at 80 degrees Fahrenheit. What is the slope of the graph of a linear equation that models the temperature T as a function of the number of chirps per minute N?
