Problem 1


An educator wants to see if there is a relationship between the number of absences for a student and the student’s final grade. Use the data below to find the least squares prediction line and to answer the questions 32 - 34:
Absences    10 12  2    0   8   5
Final Grade 70 65 96 94 75 82

Based on this line, what would the average grade be for a student who missed 6 days of class?


What does x = 0 represent?


What average grade does the model predict for students who have perfect attendance?
