The majority of Garfield's business comes from orders placed by homeowners who are trying to keep neighborhood dogs out of their yards. Garfield's operating information for the first six months of the year follows: Month January February March April May June Number of Bottles Sold 1,050 1,370 1,760 2,410 3,390 3,700 Operating Cost $ 10,460 15,700 15,930 19,790 27,460 34,670 Required: 3. Using the high-low method, calculate Garfield's total fixed operating costs and variable operating cost per bottle. (Do not round your intermediate calculations. Round your variable cost per unit answer to 2 decimal places and fixed cost answer to the nearest whole number.) Answer is complete but not entirely correct. $ 9.14 Variable Cost per Unit Fixed Cost 863 4. Perform a least-squares regression analysis on Garfield's data. (Use Microsoft Excel or a statistical package to find the coefficients using least-squares regression. Round your answers to 3 decimal places.) Coefficients Intercept X Variable 1 5. Determine how well this regression analysis explains the data. (Round you regression statistics to three decimal places and your percentage answer to the nearest whole number.) Answer is not complete. Regression Statistics Multiple R 0.951 X R Square Adjusted R Square Standard Error Observations From the regression output, of the variability number of bottles explains % in Garfield's total about cost. 6. Using the regression output, create a linear cost equation (y= a +bx) for estimating Garfield's operating costs. (Round your answers to 3 decimal places.) Total Cost = + (Number of Bottles)
