Using the regression formula with a slope = 0.904 and an intercept = 0.719,what would the predicted college GPA be for a student whose current high school GPA = 3.2?
A) 2.69
B) 2.33
C) 3.61
D) 3.20
Slope
The measure of the steepness or incline of a line, typically representing the rate of change between two variables in a linear relationship.
Intercept
The point where a line crosses the y-axis in a graph, representing the value of the dependent variable when the independent variable is zero.
Predicted GPA
An estimate of a student's grade point average based on various predictive factors or models.
- Utilize linear regression equations to forecast results from specified predictor variables.

Final Answer :
C
Explanation :
The regression formula is:
predicted college GPA = slope(hs GPA) + intercept
Substituting the given values:
predicted college GPA = 0.904(3.2) + 0.719 = 3.6118
Rounding off to two decimal places:
predicted college GPA = 3.61
Therefore, the predicted college GPA for a student with a high school GPA of 3.2 is 3.61, which is Option C.
predicted college GPA = slope(hs GPA) + intercept
