A real estate agent wants to predict the selling price of single-family homes from the size of each house. A scatterplot created from a sample of houses shows an exponential relationship between price, in thousands of dollars, and size, in 100 square feet. To create a linear model, the natural logarithm of price was taken and the least-squares regression line was given as ln(priceˆ)=2. 08+0. 11(size). Based on the model, which of the following is closest to the predicted selling price for a house with a size of 3,200 square feet?.
