Extracted text: Use the given data to find the best predicted value of the response variable. Based on the data from six students, the regression equation relating number of hours of preparation (x) and test score (y) is y= 67.3 + 1.07x. The same data yield r= 0.224 and y = 75.2. What is the best predicted test score for a student who spent 2 hours preparing for the test? 59.7 78.1 69.4 75.2
