The Hard Rock Mining Company is developing cost formulas for management planning and decision making purposes. The company's cost analyst has concluded that utilities cost is a mixed cost, and he is attempting to find a base with which the cost might be closely correlated. The controller has suggested that tons mined might be a good base to use in developing a cost formula. The production superintendent disagrees; she thinks that direct labor hours would be a better base. The cost analyst has decided to try both bases and has assembled the following information:
Tons Mined Labor_Hours Utilities
Quarter (000) (000) Cost
First ............. 15 5 $ 50,000.00
Second ............. 11 3 $ 45,000.00
Third ............. 21 4 $ 60,000.00
Fourth ............. 12 6 $ 75,000.00
First ............. 18 10 $100,000.00
Second ............. 25 9 $105,000.00
Third ............. 30 8 $ 85,000.00
Fourth ............. 28 11 $120,000.00
1. Using tons mined as the independent (X) variable:
a. Determine a cost formula for utilities cost using the least-squares regression method. (The variable cost you compute will be in thousands of tons. It can be left in this form, or you can convert your variable cost to a per ton basis by dividing it by 1,000)
B. Prepare a scatter graph and plot the tons mined and utilities cost. (Place cost on the vertical axis and tons mined on the horizontal axis.) Fit a straight line to the plotted points using the cost formula determined in (a) above.
2. Using direct labor-hours as the independent (x) variable, repeat the computations in (a) and (b) above.
3. Would you recommend that the company uses tons mined or direct labor- hours as a base for planning utilities cost?© BrainMass Inc. brainmass.com October 24, 2018, 10:21 pm ad1c9bdddf

Change Management Plan Paper and Defense
For this assignment you will develop a change management plan for CrysTel, the organization in the "Building a Culture for Sustaining Change" Simulation. Develop a paper in which you do the following:
a. Identify the major implications of the change at CrysTel, including any human behavior implications.
b. Select an appropriate change model for CrysTel. Develop a plan that addresses human variables and potential resistance to change. Be sure to include contingency strategies for managing any resistance.
c. Select an appropriate leadership style for successfully implementing the change at CrysTel. Recommend management and leadership practices that will contribute to the continuing success of the change.
d. Recommend measures to monitor the progress of the change at CrysTel.
e. Analyze three future leadership challenges that CrysTel might face in the next 5 to 10 years.
