To create a scatter plot, draw a line of best fit, and interpret the slope and y-intercept, a good statistical question needs to involve two quantitative variables for correlation analysis. From the options presented, the suitable questions are:
C. How is college student enrollment changing over the last century?
(This question suggests a time series analysis where you could plot years against enrollment numbers.)
E. How tall are the students in your grade level at school?
(This question focuses on the height of students, allowing for a scatter plot of individual heights.)
The other options (A, B, D, F) are either categorical (A, B, D) or historical/percentage-focused (F), which would not yield the quantitative data needed for a scatter plot and line of best fit.
