Use the Given Data to Find the Best Predicted Value $\hat { y } = 2 + 3 x . \text { Also, } \bar { y } = 5.0 \text {. }$

Use the given data to find the best predicted value of the response variable. Ten pairs of data yield r=0.003 and the regression equation $\hat { y } = 2 + 3 x . \text { Also, } \bar { y } = 5.0 \text {. }$
What is the best predicted value of y for x=2 ?

A) 7.0
B) 5.0
C) 8.0
D) 17.0
