Crescent Oil has developed three new blends of gasoline – Blend X, Blend Y and Blend Z, and must decide which blend or blends to produce and distribute. A study of the miles per gallon ratings of the three blends is being conducted to determine if the mean ratings are the same for the three blends.

Five automobiles- 1, 2 3, 4 and 5, have been tested using each of the three gasoline blends and the miles per gallon ratings are shown on the accompanying Excel spreadsheet.

Based on the sample data we would like to determine whether the different blends of gasoline, produce significant differences in the average mpg. We would like to use the methods we have learnt so far in 361A to see if our result is statically significant. (Statistical significance refers to a result that is not likely to occur randomly but rather is likely to be attributable to a specific cause – in this case the different gasoline blends and different cars.)

Carry out the following tests and make preliminary findings:

1. For the sample data, calculate the means and standard deviations for the mpg for each of the three blends of gasoline – Blend X, Blend Y and Blend Z.
2. Draw three boxplots using Excel for mpg, one for each blend of gasoline.
3. Run three two sample t-tests between the different blends of gasoline i.e. compare the means of Blend X and Blend Y, then Blend X and Blend Z and finally Blend Y and Blend Z. Are they the same or are they different?
4. Armed with this information above determine whether or not your results show that the three different gasoline blends produce the same average mpg or not. Your answers should specifically site the information you re using to make your determination.
5. Re-run parts 1 - 4 above but this time your focus is on the mpg of each car for the 5 cars (car 1 through car 5) not for the three gasoline blends.

Your report should have the following sections, arranged sequentially:

1. Introduction and problem background

2. Data description and the business questions to be answered

3. Initial data exploration – descriptive statistics/graphs

4. Analyses

5. Interpretation of results, deficiencies in methods, final conclusions and recommendations for decision-making

Gallatin Carpet Cleaning is a small, family-owned business operating out of Bozeman, Montana. For its services, the company has always charged a flat fee per hundred square feet of carpet cleaned. The current fee is $23.15 per hundred square feet. However, there is some question about whether the company is actually making any money on jobs for some customers—particularly those located on remote ranches that require considerable travel time. The owner’s daughter, home for the summer from college, has suggested investigating this question using activity-based costing. After some discussion, she designed a simple system consisting of four activity cost pools. The activity cost pools and their activity measures appear below:

The total cost of operating the company for the year is $355,000 which includes the following costs:

Resource consumption is distributed across the activities as follows:

Job support consists of receiving calls from potential customers at the home office, scheduling jobs, billing, resolving issues, and so on.

Required:

1. Prepare the first-stage allocation of costs to the activity cost pools.

2. Compute the activity rates for the activity cost pools.

3. The company recently completed a 600 square foot carpet-cleaning job at the Flying N Ranch—a 52-mile round-trip journey from the company’s offices in Bozeman. Compute the cost of this job using the activity-based costing system.

4. The revenue from the Flying N Ranch was $138.90 (600 square feet @ $23.15 per hundred square feet). Calculate the customer margin earned on this job.
