Based on the data...

Based on the data from six students, the regression equation relating number of hours of preparation (x) and test score (y) is y-hat = 67.3 + 1.07x. The same data yield r = 0.224 and y-bar = 75.2. What is the best predicted test score for a student who spent 5 hours preparing for the test?
