Data Set 6-10: The correlation between a score based on anthropometric measurements (height, strength, reaction time and others) and college GPA is .05. Your task will be to predict GPA, given the anthro measurements. Be sure you set this up properly and work precisely (3 or 4 decimal places.).
$$\begin{array} { l c r }
& \underline{ \text { GPA }} & \underline{ \text { Anthro }} \
\text { Mean } & 2.6 & 20 \
\text { Standard Deviation } & 0.7 & 4
\end{array}$$
-Based on Data Set 6-10, predict a GPA for a person whose anthro data score was 15.
A) 1.2
B) 2.6
C) 4.0

The correlation between the anthropometric score and GPA is very low (.05), indicating almost no linear relationship. Therefore, the best prediction for any given anthro score, without more specific information, would be the mean GPA of the dataset, which is 2.6.
