A company would like to estimate its total cost equation. It hascollected 48 months of monthly production output and correspondingtotal production costs. The collected data is in thefile Production Cost Data Only.xlsx.Recall that
TOTAL COST = Fixed Costs + Variable Cost per Unit *Output.
Use the data to estimate a function that describes total costfor this company. (Round answers to 2 decimal places)
Develop a scatterplot of the two variables: monthly output andmonthly total costs. Describe the relationship.
Estimate a total cost curve for this company. Statethe estimated total cost function.
Based on your estimated total cost curve what is the estimatedFixed Cost for the Company?
Based on your estimated total cost curve what is the estimatedaverage unit variable cost for the Company?
Develop a 95% confidence interval for the true average variablecost per unit.
What percent of the variation in monthly production costs is“explained” by the monthly production output?
Suppose the plant manager is interested in meancosts for several monthswhere output averages 30,000units (i.e., Xp = 30). What is the predicted monthly total costswhen output averages 30? Construct a 95% confidenceinterval for the mean production costs for months that average30,000 units of output.
Monthly Output (in thousands of units) | Monthly Total Production Cost (in thousand $) |
