For 50 randomly selected students enrolled in both a developmental math course and a developmental English course, ratings by each student of their math instructor's teaching skills (x) are recorded along with the ratings of their English instructor's teaching skills (y); the ratings range from 1 to 10. The 50 paired ratings yield x=6.3, y=6.0, r=−0.155, P-value=0.284, and y=7.08−0.177x. Find the best predicted value of y (rating of the English instructor's teaching skills) for a student whose rating of their math instructor's teaching skills is x=4. Use a 0.1 significance level.
