Question
The data in the table below show five students' reading test grade and final exam grade in a history class.
Reading test score, x | 8.5 | 9.4 | 10.0 | 11.4 | 12.0 |
---|---|---|---|---|---|
History final exam grade, y | 64 | 68 | 76 | 87 | 92 |
(a)
Use the points (8.5, 64) and (10.0, 76) to find a linear model that will predict a student's final exam grade given his or her reading test score.
f(x) =
(b)
Use your linear model to estimate a student's final exam grade in the history class given that the student's reading test grade was 9.9. Round to the nearest whole number.
