C21 fx A B D E The following data has the quantity sold of an item for different prices. We would like to see whether there is a linear relationship between price (independent variable) and quantity sold (dependent variable). 3 Construct the appropriate regression model of these two variables. Using the regression model, calculate MAPE for the data. MAPE = \begin{tabular}{|c|c|c|c|c|} \hline Price (\$) & Quantity Sold & Forecast & Error & |Percentage Error| \\ \hline 2 & 7500 & & & \\ \hline 5 & 5400 & & & \\ \hline 3 & 7000 & & & \\ \hline 3.5 & 6500 & & & \\ \hline 2.5 & 7500 & & & \\ \hline 4.5 & 6000 & & & \\ \hline 4 & 5500 & & & \\ \hline \end{tabular}
