Reference no: EM13119895

In an art class, students were tested at the end of the course on a final exam. Then they were retested with an equivalent test at subsequent time intervals. their scores after time x in months, are give in the following table

Time, X (in months) Score, y

1 84.9%

2 84.6

3 84.4
