Answer:
c. 4.27
Step-by-step explanation:
We have been given the regression equation of for predicting number of speeding tickets (Y) from information about driver age (X) as [tex]Y=-0.065(X)+5.57[/tex].
To find the predicted number of tickets for a twenty-year-old, we will substitute [tex]X=20[/tex] in our given equation.
[tex]Y=-0.065(20)+5.57[/tex]
[tex]Y=-1.3+5.57[/tex]
[tex]Y=4.27[/tex]
Therefore, the predicted number of tickets for a twenty-year-old would be 4.27 tickets.
