One of Nature's Patterns Connects the Percent of Adult Birds

Multiple Choice

One of nature's patterns connects the percent of adult birds in a colony that return from the previous year and the number of new adults that join the colony. Here are data for 13 colonies of sparrowhawks (a type of bird) and the software output:

$$\begin{array} { | l | l | l | l | l | l | l | l | l | l | l | l | l | l | } \hline \text { Percent return } & 74 & 66 & 81 & 52 & 73 & 62 & 52 & 45 & 62 & 46 & 60 & 46 & 38 \\\hline \text { New adults } & 5 & 6 & 8 & 11 & 12 & 15 & 16 & 17 & 18 & 18 & 19 & 20 & 20 \\\hline\end{array}$$ ?
Simple linear regression results:
Dependent Variable: New adults
Independent Variable: percentage return
New adults $= 31.934259 - 0.30402295$ percentage return
Sample size: 13
$R$ (correlation coefficient $) = - 0.7484673$
$\mathrm { R } - \mathrm { sq } = 0.5602033$
Estimate of error standard deviation: $3.6668913$

Parameter estimates:

$\begin{array}{|l|r|r|r|r|r|r|}\hline \text { Parameter } & \text { Estimate } & \text { Std. Err. } & \text { Alternative } & \text { DF } & \text { T-Stat } & \text { p-value } \\\hline \text { Intercept } & 31.934259 & 4.8376164 & \neq 0 & 11 & 6.6012383 & <0.0001 \\\hline \text { Slope } & -0.30402295 & 0.081220034 & \neq 0 & 11 & -3.7432014 & 0.0032 \\\hline\end{array}$ A scatterplot of the data shows that there is a linear relationship between the percent x of adult sparrowhawks that return to a colony from the previous year and the number y of new adult birds that join the colony.
What is the least-squares regression line for predicting y from x

A) ? = 31.934 - 0.304x
B)
? = -0.304 + 31.934x
C) ? = -31.934 + 0.304x
D) ? = 0.304 - 31.934x
