question 9

Multiple Choice

Ten students in a graduate program at Carleton University were randomly selected.Their grade point averages (GPAs) when they entered the program were between 11.5 and 12.0.The following data were obtained regarding their GPAs on entering the program versus their current GPAs. $$\begin{array} { c c } \text { Entering GPA (E) } & \text { Current GPA (C) } \\11.5 & 11.6 \\11.8 & 11.7 \\11.6 & 11.9 \\11.6 & 11.6 \\11.5 & 11.9 \\11.9 & 11.8 \\12.0 & 11.7 \\11.9 & 11.9 \\11.5 & 11.8 \\11.7 & 12.0\end{array}$$

• A) \(\hat{C}\) = 10.51 + 0.329E
• B) \(\hat{C}\) =12.23 + 0.746E
• C) \(\hat{C}\) = 11.42 + 0.0312E
• D) \(\hat{C}\) = 13.81 + 0.497E
