I need help with project. It needs to be about 12 pages. Details below:

The Problem Statement:
• Dupree sell heating oil to residential customers
• Customers may run out of oil
• Dupree wants to guarantee that the customer’s oil tank will never run dry.
• Dupree pledges “50 free gallons” in case a tank runs dry• To estimate customers’ oil usage, the home heating industry uses the concept of “degree days.”
Degree day is equal to the difference between the average daily temperature and 68 degrees
Fahrenheit. For ex. (68 – 50) = 18 (if negative, it will be changed to “zero”).Using degree days and the tank size, the oil industry can estimate when the customer is getting low on fuel and when to resupply the customer.• The data gathered from customers is given in the
DUPREE.XLS file:
The # of gallons of oil_usage and the # of degree days since last oil fill for 40 customers # of people residing in homes of the 40 customers (more hot water usage)
Assessment by staff, of home type classification (1-5), is a composite index of the home size, age, exposure to wind, level of insulation, and furnace type. A low home_factor index implies a lower oil consumption per degree day.• Use data in DUPREE.XLS to see whether a statistically reliable oil consumption model can be estimated from the data.
• SomeAdditional Project Guidelines:
About 10 to 15 quality pages (concise)
Using the materials used in this course and beyond propose the best model
Using the automated variable selection procedures find the best model
Compare the above two models and propose your best possible model
Provide a summary of different models used and justify the best model
Define the parameters of the proposed model
Demonstrate the use of the model through examples
Would you recommend any explanatory variables to be omitted.
Would you recommend any other explanatory variables that could be added to the model?

    Q2. In order to determine the excess amount of gas that had to be bought from Distrigas we made an assumption that the demand was not normally distributed and in order to normalize it we removed the deviation of 18.66 from the average of the independent demands over the three months to arrive at a normalized value of 178 (rounded off). The assumption is that the gas Utility companies will buy gas from Distrigas only if the demand goes aboce 178. Following this methodology the gas utility company will need to purchase 1801 MMcf from Distrigas to fulfill the peak demand.…

    My experiment worked out the way I thought it would. My predictions were correct. My last prediction is debatable, for it did get bigger and harder. Although, it may not have gotten hard from the salt water. Throughout the experiment, the egg grew smaller and bigger. This was because different substances react differently to the egg. Some substances would go in while others wouldn't. This is an example of how a cell is selectively permeable. In the lab, there were possible sources of error. When we were measuring the circumference of the egg, we used string. Some people may have stretched the string out resulting in a vary of incorrect results. Also, the volume measurements…

    Dupree Fuels Company sells heating oil to residential customers. The company wants to guarantee to its customers that they will not run out of heating oil at any time during the winter months. Factors such as the energy efficiency of homes and the temperatures during winter months have been shown to be important factors related to the amount of heating oil that customers use. The company collected data from a sample of 40 residential customers regarding four variables, oil usage, degree days, a measure of the difference in temperature from 68 degrees Fahrenheit over the period since the last tank fill up, the number of people living in the home, and a home index that measures the energy efficiency of the homes. The results of the linear regression models that were tested showed that degree days and the home index were significant predictors of heating oil usage. Based on the results of the linear regression analysis, a forecast was created to predict the amount of heating oil customers would use based on an average home index.…

    Hence, the temperature is supposed to be observed on a regular basis regardless of the manufacture phase. The same solution can be applied to the excessive use of water for recycling. Besides that, however, operation manager and related personnel are responsible for a reasonable calculation of water consumption per working cycle. In this case, a zero approach is required: a pilot round should be conducted with no water and then with a little amount so that it could be possible to indicate the most apt amount on the basis of comparison (Basu & Wright 2005). As for the excessive torque of the main engine, it has to be indicated that it should be set at the initial stage of the maintenance. The maintenance manager is responsible for the starting data so that torque could be regulated in advance. The best solution to such problem is the initial choice of an asset with needed engine torque. Regarding the overloading of the asset, the amount and frequency of loads are usually controlled by operation manager as long as he or she is expected to make the best judgement of the schedule, capacity of the asset and economy considerations. On the contrary, the performance with a little load but the same parameters is an evident result of the employee’s failure to report about minimal load and set the relevant parameters. The…

    Summary of the article :In 2005 Hurricane Katrina caused massive shortage on natural gas and fuel in the USA.Due to the location of the hurricane in southern USA, agricultural shipping, fuel production and processing and transport were all affected. On the global market, all of these were already in high demand.As a result of the increase in natural gas prices, fertilizers costs, residential heating and electricity rates rise since they are complementary goods.Another effect of the natural gas prices, some fertilizing plants chose to close while others decided to cut production.On top of all of these factors, a frigid winter would incrementally increase prices unless people would be willing to conserve the natural gas or if the efficiency improves.In conclusion, the growth of demand increases while the supply reduces as storage inventories decrease.…
