To solve this numerically, we need to: 1. Calculate the predicted values ($\hat{Y}$) using the given regression equation: \[ Y = 2.6185 + 0.4369 X \] where $X$ is the number of customers (in hundred). 2. Find the residuals ($e_i$) using: \[ e_i = Y_i - \hat{Y}_i \] where $Y_i$ is the actual monthly sales and ______ ____ ____ _______ ______ __________ _________.
