question 117

Multiple Choice

Write the best-fit linear model for the data.
-Ten students in a graduate program were randomly selected. Their grade point averages (GPAs) when they entered the program were between 3.5 and 4.0. The following data were obtained regarding their GPAs on entering the program
Versus their current GPAs. Find a linear function that approximates a student's current GPA as a function of his or her
Entering GPA. $\begin{array}{cc}\text { Entering GPA } & \text { Current GPA } \\\hline 3.5 & 3.6 \\3.8 & 3.7 \\3.6 & 3.9 \\3.6 & 3.6 \\3.5 & 3.9 \\3.9 & 3.8 \\4.0 & 3.7 \\3.9 & 3.9 \\3.5 & 3.8 \\3.7 & 4.0\end{array}$

• A) \(y = 3.67 + 0.0313 x\)
• B) \(y = 2.51 + 0.329 x\)
• C) \(y = 5.81 + 0.497 x\)
• D) \(\mathrm { y } = 4.91 + 0.0212 \mathrm { x }\)
