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.)
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.)

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.)

of the variability in Garfield’s total
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.)
