Suppose the following table was generated from sample data of 20 employees relating hourly wage to years of experience and whether or not they have a college degree. Using statistical software, create an indicator (dummy) variable for the variable "Degree" and find the regression equation. Is there enough evidence to support the claim that on average employees with a college degree have higher hourly wages than those without a college degree at the 0.05 level of significance? If yes, write the coefficient of the dummy variable in the space provided, rounded to two decimal places. Else, select "There is not enough evidence."

Rusty Williams, the owner and CEO of The Rusty Bicycle Company, a small manufacturer and distributer of recreational bikes, has dejectedly watched sales of his company’s flagship bike, the WindRunner, decline precipitously over the past 7 years. Believing that the trend is irreversible, Rusty has taken the drastic step of shutting down the operation of his firm in an effort to reduce costs while he tries to figure out how to rescue the firm he has spent the bulk of his life building.

Rusty asks his brother John, the head design engineer at his firm to design and build a prototype of a new bicycle that might be able to save the company. Rusty tells John to forget about conventional bicycle design and to “think big” and come up with something truly revolutionary.

After about 6 weeks of intense work, John comes back to Rusty with a proposal for the “WindRunner 2.0”, a bicycle unlike anything else on the market today. John believes that the specialty nature of the new bicycle suggests that, while unit sales volume may be relatively low, the bicycle should command a premium sales price. Specifically, he thinks that customers would be willing to pay upwards of $845 per bike.

Rusty, intrigued by the new design, hires a market research consultant, Sandy Frazier, to study the potential demand for the WindRunner 2.0. As projecting demand for a completely new product is notoriously difficult, she limits her prediction to a 5 year horizon. Sandy gives the following forecast to Rusty in exchange for her customary fee of $45,000.

Rusty is optimistic that the expected sales revenue will be enough to save his company. Deciding to move forward on the evaluation of this project, he asks John what new manufacturing capacity will be needed to begin production. John thinks that he could reconfigure the firm’s current manufacturing facility to produce the new model bicycle, although the current production machinery, purchased over 20 years ago, is woefully inadequate. He estimates that the necessary new equipment could be purchased for $2.5 million and that the whole manufacturing process will incur fixed operating costs of $3 million per year. Additionally, he estimates the variable costs of production to run $260 per bike produced.

John further thinks that the existing production equipment, which will no longer be needed, could be sold for $400,000. The existing equipment was classified for tax purposes under the 15 year MACRS category. As a result of a recent exemption given to small businesses, Rusty will not have to use the MACRS depreciation schedules for new capital assets acquired. Instead, the new equipment will be depreciated straight-line to zero over the 5 year planning horizon. John thinks that the new production equipment will be worthless and scrapped at the end of 5 years.

Finally, John tells Rusty that he will need about $300,000 in raw materials (i.e. parts and supplies) for the bicycles to begin production. This expenditure will not be recovered at the end of the project. Rusty, worried about spending so much cash on parts, calls a supplier, Rodney Murdock, to see about short-term credit options. Unfortunately, due to the precarious position Rusty finds his company in, the supplier is unable to offer any credit terms and will insist upon cash on delivery payment for raw materials.

Recently, a federal government economic stimulus measure was enacted. As a result of this effort, small businesses, like Rusty, will have their business income tax rate cut to zero percent for the next 10 years. The intent is to stimulate the formation of new small businesses throughout the country. Since this project is a last ditch effort to save the company, Rusty plans to let the project run for the 5 year forecast horizon. After that, he plans to dissolve the business and retire. Due to the desperation involved in this project, Rusty estimates that a 20% required rate of return is appropriate.

Rusty has asked for your help in addressing the following questions.

Prepare a 5 year forecast of cash flow from assets (CFA) for the WindRunner 2.0 project.

Calculate the Net Present Value (NPV) of the WindRunner 2.0 project.

Since the future of his company rests on the success or failure of this project, Rusty is understandably concerned about risks to his forecasts and expectations for the project. To get a better picture of the risk involved, Rusty again asks you to conduct the following scenario analyses.   

With your previous work being used as the ‘base case’ scenario, estimate the net present value of the project under a pessimistic scenario. Specifically, Rusty wants to consider the project’s NPV if both sales volume and the sales price are 10% below the base case scenario, while variable costs are 10% above the base case scenario estimates. All other variables will remain the same.

Now, to look at the optimistic case, reevaluate the project NPV where sales volume and sales price are 10% above the base case estimates, while variable costs are 10% below base case estimates. Again, all other variables are presumed to remain the same.

Finally, Rusty would like to know what minimum quantity of the WindRunner 2.0 models will have to be sold in order to produce a zero NPV (i.e. the financial breakeven point). That is, he would like to know what level of sales volume would leave him indifferent between undertaking the project versus shelving the project.  

Greg’s Bicycle Shop has the following transactions related to its top-selling Mongoose mountain bike for the month of March. Greg's Bicycle Shop uses a periodic inventory system.

For the specific identification method, the March 5 sale consists of bikes from beginning inventory, the March 17 sale consists of bikes from the March 9 purchase, and the March 27 sale consists of four bikes from beginning inventory and eight bikes from the March 22 purchase.

Calculate ending inventory and cost of goods sold at March 31, using the specific identification method.

Using FIFO, calculate ending inventory and cost of goods sold at March 31.

  Using LIFO, calculate ending inventory and cost of goods sold at March 31.

Using weighted-average cost, calculate ending inventory and cost of goods sold at March 31. (Round your intermediate and final answers to 2 decimal places.)

Calculate sales revenue and gross profit under each of the four methods. (Round weighted-average cost amounts to 2 decimal places.)

7. If Greg’s Bicycle Shop chooses to report inventory using LIFO instead of FIFO, record the LIFO adjustment.

Green Thumb Gardening is a small gardening service that uses activity-based costing to estimate costs for pricing and other purposes. The proprietor of the company believes that costs are driven primarily by the size of customer lawns, the size of customer garden beds, the distance to travel to customers, and the number of customers. In addition, the costs of maintaining garden beds depends on whether the beds are low maintenance beds (mainly ordinary trees and shrubs) or high maintenance beds (mainly flowers and exotic plants). Accordingly, the company uses the five activity cost pools listed below:

The company already has completed its first stage allocations of costs and has summarized its annual costs and activity as follows:
