The data from data216.dat contains information on 78 seventh-grade students. We want to know how well each of IQ score and self-concept score predicts GPA using least-squares regression. We also want to know which of these explanatory variables predicts GPA better. Give numerical measures that answer these questions. (Round your answers to three decimal places.)

(Regressor: IQ) R 2 =

(Regressor: Self-Concept) R 2 =

Which variable is the better predictor?

Restaurant Pricing. Consider a restaurant that charges $10 for all, you can eat and has 20 customers at this price. The slope of the demand curve is minus−​$0.20 per​ meal and the marginal cost of providing a meal is ​$66.

​1.) Use the line drawing tool to draw and label the demand line.

​2.) Use the line drawing tool to draw and label the marginal revenue line.

​3.) Use the line drawing tool to draw the marginal cost line.

Carefully follow the instructions​ above, and only draw the required objects.

The​ profit-maximizing quantity is __ meals. ​(Enter your response rounded to the nearest​ unit.)

The​ profit-maximizing price is ​$___. ​(Enter your response rounded to the nearest​ dollar.)

Q4 Hotel California has 160 rooms. The hotel has an ample low-fare demand at the room rate of $200 per night, but the demand from the high-fare class which pays $450 per night on average, is uncertain. Table below shows the number of high-fare rooms that were booked during the past 30 days. How many rooms should Hotel California protect for high-fare customers to maximize its expected revenue? (6 points)

iKiwi wants to be able to analyse sales information from all its stores so that any opportunities to increase revenue can be identified and acted on. They also want to be able to track product returns for quality control purposes. You are the Chief Knowledge Officer and have been asked to create two Data Warehouses:

1. Create a Data Warehouse schema (with one central table and at least four lookup tables) that iKiwi can use to monitor sales performance. Provide some context for your schema. 2. Create another Data Warehouse schema (with one central table and at least four lookup tables) to monitor products returned by customers. Provide some context for your schema.

1, Which of these is NOT a component of the Business Model?

A) The value proposition

B) The target market

C) the competition

2, Wang, Digital, Data General, Prime, and other computer companies were all created in northeastern Massachusetts! They felt that computing was professional and not personal. Computers were to be controlled by operators and not end-users. These minicomputer makers failed to see how the microcomputer would make computing ubiquitous. None of them exist today. We refer to their reason for failure as:

A) Utterly unsound economics

B) A business concept blind spot

C) An inability to compete with larger customers

D) Loss of key leadership when the founders retired.

D) the revenue sources

E) all of the above are components of the business model.

The sandwich shop is a restaurant that serves only one item, the ham sandwich. The restaurant serves two groups of customers, younger adults and senior citizens. The two segments have the following demand functions: younger adults, Q_y = 5,000 – 10P_y and senior citizens, Q_s = 10,000 – 100P_s. The restaurant has constant marginal cost of $10 and no fixed costs.

(4)a. Write the inverse demand and marginal revenue functions for each segment of the ham sandwich market.

(4)b. What are the profit maximizing price and quantity for each segment and how much profit will he earn?

(4)c. What are the price elasticities of demand for each segment at the prices and quantities you determined in part “b”

Let’s assume you were hired by Panera Bread( a restaurant with fast service and healthy options) to restructure how this business operates with the following goals in mind:

1. Increase customer service by decreasing negative comments on customer comment cards
2. Create a physical redesign that increases efficiency for customers and employees, and
3. As a result of the reorganization, increase store overall revenue by 7% in the next year

What model(s) would you use to meet these goals? How would you use what you learned about organizing to manage these changes? What needs to be done first? second? etc. make sure the plan you put in place allows you to meet the goals identified.

Gillian Shaw opened Shaw's Carpet Cleaners on March 1. During March, the following transactions were completed.

Change in Estimate versus Error Correction Facts: Your company, PlumbAll, provides routine and quick response plumbing services to a range of corporate customers. Customers are expected to pay on the first of each month, in advance of receiving services. One of your customers is a private school that has been a longtime customer. The customer has not paid for the last four months of services (September–December 20X1); nevertheless, to maintain a positive relationship, your company continued to provide services during that time. Your company ceased providing services in January 20X2 and found out in that same month that the school filed for bankruptcy in August. You now believe that the collection of the missed payments is extremely unlikely. Your company has already issued financial statements to lenders (for the period ending 12/31/X1) that reflected revenue and a corresponding account receivable related to this customer of $11,000 per month for services provided to this customer. Those financial statements also reflected the company’s standard allowance (reserve) amount on receivables of 3% of sales. In total, your company’s average monthly sales amount to $300,000.

Required:

1. Evaluate whether receipt of this information indicates you have a change in estimate or whether the customer’s bankruptcy results in this event being considered an error in previously issued financial statements.

2. Describe the accounting treatment required by the Codification for each alternative. Support your explanations with draft journal entries.

3. Briefly state which treatment appears to be more appropriate given the circumstances, describing any assumptions you made in concluding.
