It seems reasonable that there would be a relationship between the amount of time a student spends studying and their GPA. Suppose you were interested in predicting a student’s GPA based on the hours they study per week. You were able to randomly select
students and obtain this information from each student.

Without technology, make a scatterplot.

Estimate a line of best fit (use a ruler and “eyeball” it), and determine its equation.

Interpret the slope and
-intercept in context.

Describe the association.
