Ten Students in a Graduate Program at the University of Toronto

question 39

Multiple Choice

Ten students in a graduate program at the University of Toronto were randomly selected.Their grade point averages (GPAs) when they entered the program were between 3.5 and 4.0.The students' GPAs on entering the program and their current GPAs were recorded. Dependent variable is: Current GPA
R-squared = 0.677968
S =0.024768 with 10 - 2 = 8 degrees of freedom $$\begin{array} { l l l l l } \text { Variable } & \text { Coefficient } & \text { SE(Coeff) } & \text { t-ratio } & \text { P-value } \\\text { Constant } & 3.584756 & 0.078183 & 45.85075 & 5.66 \times 10 ^ { - 11 } \\\text { Entering GPA } & 0.090953 & 0.022162 & 4.103932 & 0.003419\end{array}$$

• A)Entering GPA = 3.584756 + 0.090953 × Current GPA; We estimate that the entering GPA for these students increases by 0.090953 points for each 1 point increase in their current GPA.
• B)Current GPA = 3.584756 + 0.090953 × Entering GPA; We estimate that the current GPA for these students increases by 3.584756 points for each 1 point increase in their entering GPA.
• C)Current GPA = 3.584756 × Entering GPA + 0.090953; We estimate that the current GPA for these students increases by 3.584756 points for each 1 point increase in their entering GPA.
• D)Current GPA = 3.584756 + 0.090953 × Entering GPA; We estimate that the current GPA for these students increases by 0.090953 points for each 1 point increase in their entering GPA.
• E)Current GPA = 3.584756 × Entering GPA + 0.090953; We estimate that the current GPA for these students increases by 0.090953 points for each 1 point increase in their entering GPA.
