750 7000a. Use data to develop an estimated regression equation that could be used to predict the total cost for a given prodcution volume?
b. What is the variable cost per unit produced?
c. Compute the coefficient of determination. What percentage of the variation in total cost can be explained by prodcution volume?
d. The companys production schedule shows 500 units must be produced next month. What is the estimated total cost for this operation?
Note: I am attaching an example of the formulas/answers I need to show that are similar to this one.
