The Common Cricket Can Be Used as a Crude ThermometerCompute the Least-Squares Regression Line for Predicting the Temperature from the Colder

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.
$\begin{array}{cc}\hline \begin{array}{c}\text { Chirp Rate } \\\text { (chirps/second) }\end{array} & \begin{array}{c}\text { Temperature } \\\left({ }^{\circ} \mathrm{F}\right)\end{array} \\\hline 2.4 & 61.9 \\3.8 & 83.6 \\3.7 & 71.8 \\2.0 & 47 \\3.4 & 65.1 \\3.9 & 75.8 \\\hline\end{array}$
Compute the least-squares regression line for predicting the temperature from the chirp ra

A) $y = 14.354 + 21.6004 x$
B) $y = 21.6004 + 19.2632 x$
C) $y = 19.2632 + 21.6004 x$
D) $y = 21.6004 + 14.354 x$
