APFIVE Logarithmic Regression Model Prediction
Consider a data set where the relationship between x and y is modeled by the equation $$y = a + b\log_{10}(x)$$. A least-squares regression line is fitted to the transformed data set $$(\log_{10}(x), y)$$ and is given by $$y = 2 + 3\log_{10}(x)$$. What is the predicted value of $$y$$ when $$x = 10$$?
