An exponential relationship exists between the explanatory variable and the response variable in a set of data. The common logarithm of each value of the response variable is taken, and the least-squares regression line has an equation of log (4) = 7.3 - 1.5x. Which of the following is closest to the predicted value of the response variable for x = 4.8 ? (A) 0.1 (B) 0.68 (C) 1.105 (D) 1.26 (E) 14.5
