The Common Cricket Can Be Used as a Crude Thermometer

Multiple Choice

The common cricket can be used as a crude thermometer. The colder the temperature, the slower the rate of chirping. The table below shows the average chirp rate of a cricket at various temperatures.
$\begin{array} { c c } \hline \begin{array} { c } \text { Chirp Rate } \\\text { (chirps/second) }\end{array} & \begin{array} { c } \text { Temperature } \\\left( { } ^ { \circ } \mathrm { F } \right) \end{array} \\\hline 1.9 & 47.7 \\2.7 & 67.7 \\2.8 & 65.4 \\1.4 & 42.8 \\1.7 & 54.7 \\3.0 & 63.3 \\\hline\end{array}$
The least-squares regression line for predicting the temperature from the chirp rate is $y = 25.6974 + 13.8826 x$ Predict the temperature if the chirp rate is 1.6 chirps per second.

A) 51 ºF
B) 48 ºF
C) 44 ºF
D) 22 ºF
