Since crickets are cold-blooded, their physiological processes are influenced by ground temperature. One such example is that ground temperature (F) can be used to predict the frequency of chirps (number of chirps per second) made by a ground cricket. (A chirp is a short and high-pitched sound).

Data are collected and here is the least-squares regression equation:

predicted y = 22.8 +3.41x

Which of the following statements is correct?

A. Above-average values of temperature tend to accompany below-average values of chirps per second.

B. From the given regression equation, we know that the correlation is positive and we can say what the exact value of that correlation is.

C. With each additional chirp per second, temperature increases by 3.41F.

D. None of the above.
