A Study Examined the Number of Trees in a Variety

question 25

Essay

A study examined the number of trees in a variety of orange groves and the corresponding number of oranges that each grove produces in a given harvest year. Linear regression was calculated and the results are below.

linear regression results:
Dependent Variable: oranges
Independent Variable: trees
Sample size: 9
R-sq = 0.886 s = 31394.7

$\begin{array}{|l|r|r|}\hline \text {Parameter} & \text { Estimate} & \text {Std. Err. } \\\hline \text {Constant }& 390.59 & 16328.8 \\\hline \text {Trees} & 525.84 & 71.22 \\\hline\end{array}$




-Does the value of s concern you? How might you deal with this data differently to address this problem?
