Final grade, y
88.8 85.9
83.0 80.6 77.7 73.3 63.5 68.3 65.4 62.6
(Round to three decimal places as needed.)
A. For every unit change in the final grade, the number of days absent falls by
days, on average.
B. For every day absent, the final grade falls by
on average.
C. For zero days absent, the final score is predicted to be 88.778 .
D. For a final score of zero, the number of days absent is predicted to be
days.
E. It is not appropriate to interpret the y-intercept.
(c) Predict the final grade for a student who misses five class periods and compute the residual. Is the observed final grade above or below average for this number of absences?
The predicted final grade is |. This observation has a residual of, which indicates that the final grade is
average.
