Write the best-fit linear model for the data.
-The paired data below consist of the temperatures on randomly chosen days and the amount a certain kind of plant grew (in millimeters). The linear model for this data is $\mathrm { y } = 14.6 + 0.211 \mathrm { x }$, where $\mathrm { x }$ is temperature and $\mathrm { y }$ is growth in millimeters. Use this model to predict the growth of a plant if the temperature is $57 .$
$$\begin{array} { c | c c c c c c c c c }
\text { Temp } & 62 & 76 & 50 & 51 & 71 & 46 & 51 & 44 & 79 \
\hline \text { Growth } & 36 & 39 & 50 & 13 & 33 & 33 & 17 & 6 & 16
\end{array}$$

A) 26.63 mm
B) 27.08 mm
C) 27.54 mm
D) 25.43 mm

Quizplus · Accepted Answer

The correct answer is A.The linear model for this data is $y = 14.6 + 0.211x$, where $x$ is temperature and $y$ is growth in millimeters. If the temperature is $57$, then the predicted growth of the plant is:$$y = 14.6 + 0.211(57) = 26.63$$
