(1.5, 65)
(3.5, 71)
(4.5, 98)
(6.5, 88)

Explanation:

Step1: Analyze each point

We check each ordered pair \((x,y)\) where \(x\) is the number of hours studying and \(y\) is the exam score.
For \((1.5,65)\): From the table, when \(x = 1.5\), \(y=65\)
For \((3.5,71)\): When \(x = 3.5\), \(y = 71\)
For \((4.5,98)\): When \(x=4.5\), there are two \(y\) - values: \(y = 98\) and \(y = 82\). This is an out - lier as the relationship between \(x\) (study hours) and \(y\) (score) seems to be a more gradual increase for most of the data.
For \((6.5,88)\): When \(x = 6.5\), \(y=88\)

Answer:

\((4.5,98)\)
