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) $y = 21.6004 + 14.354 x$
