The manager gives this information to the waiter who runs a regression and gets the following equation:Weekly total restaurant costs = $2453 + ($19.04 A? Number of customers per week)1. Plot the relationship between number of customers per week and weekly total restaurant costs.2. Estimate the cost equation using the high-low method and draw this line on your graph.3. Drawthe regression line on your graph. Use your graph to evaluate the regression line using the criteria of economic plausibility goodness of fit and significance of the independent variable. Is the cost function estimated using the high-low method a close approximation to the cost function estimated using the regression method. Explain briefly.4. At what point (number of customers) will the expected total cost based on the high-low equation equal the expected total cost based on the regressionequation?
