The regression equation to predict quiz scores from study time is: Y = 1.28X + 3 Predict the quiz score for someone who studies for 5 hours

Y = 9.4

Step-by-step explanation:

Given that,

The regression equation to predict quiz scores from study time is:

Y = 1.28X + 3

We need to find the quiz score for someone who studies for 5 hours

Put X = 5 in the above formula.

So,

Y = 1.28(5) + 3

Y = 9.4

So, the required score is 9.4.
