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.).
$$\begin{array} { l c r }
& \underline{ \text { GPA }} & \underline{ \text { Anthro }} \
\text { Mean } & 2.6 & 20 \
\text { Standard Deviation } & 0.7 & 4
\end{array}$$
-The b coefficient in Data Set 6-10 is
A) 5.71
B) 1.75
C) 0.175
D) 0.0088

Quizplus · Accepted Answer

The b coefficient is calculated using the formula: b = r * (SD_y / SD_x). Here, r = 0.05, SD_y = 0.7, and SD_x = 4. Thus, b = 0.05 * (0.7 / 4) = 0.00875, which rounds to 0.0088.
