Question

The final exam scores for a class are plotted versus the number of TA sessions attended. The resulting scatterplot has a line of best fit with the equation:

y = 3.85x + 53 where x is the number of TA sessions attended (out of 12).

Using this information, what would you estimate as the exam score of a student who attended five TA sessions?

Answer 1

You compute the 'estimate' by substituting x=5 in the equation of the stated line of best fit.  Easy, eh?
