The International Air Transport Association surveys business travelers to develop quality ratings for transatlantic gateway airports. The maximum possible rating is 10. Suppose a simple random sample of business travelers is selected and each traveler is asked to provide a rating for the Miami International Airport. The ratings obtained from the sample of business travelers follow. 3 7 8 9 10 10 10 9 9 9 9 8 5 6 7 7 9 8 10 9 8 7 6 8 7 9 5 3 9 10 10 9 9 8 9 8 6 10 8 4 7 3 10 8 9 8 10 10 8 8 Develop a confidence interval estimate of the population mean rating for Miami. Round your answers to two decimal places.

Problem One A heavy trucks coompany has two warehouses in Muscat and Sohar and dealerships in Salalah and Alburaimi city. Every truck that is sold at the dealerships must be delivered from one of the warehouses. On a certain duy the Salalah dealers sell 10 trucks, and the Alburaimi city dealers sell 12. The Muscat warehouse has 15 trucks available, and the Sohar warchouse has 10. The cost of shipping one truck is 50 OMR from Muscat to Salalah, 40 OMR from Muscat to Alburaimi city, 60 OMR from Sohar to Salalah, and 55 OMR from Sohar to Alburaimi city. How many trucks must be shifted from each warebouse to each dealership in order to satisfy the orders at the minimum cost?

Develop research questions for your Project Product/Service. Your questions must consist of the following:
1. A minimum of two open-ended questions
2. A minimum of two dichotomous questions (yes or no)
3. A minimum of three multiple-choice questions
4. A minimum of one semantic differential scale question with multiple parts (e.g., boring vs. interesting, happy vs. sad, XXX vs. non-XXX, etc.)
5. A minimum of two Likert scale questions (e.g., strongly agree to strongly disagree)
6. A minimum of one usage behavior question
7. A minimum of five additional questions of any type (other than demographic questions) that will provide you with relevant data for your product or service
8. Numerous demographic questions (i.e., what demographic information would be important for you to capture for your product or service?)

Use the following information to answer the next three questions:

Some new equipment under consideration will cost $2,600,000 and will be used for 4 years. Net working capital will experience a one time increase of $559,000 if the equipment is purchased. The equipment is expected to generate annual revenues of $1,800,000 and annual costs of $576,000. The project falls under the seven-year MACRs class for tax purposes, the tax rate is 32 percent, and the cost of capital is 12 percent. The project's fixed assets can be sold for $624,000 at the end of the project's life.

Show ALL your work.

a) What is the book value of the equipment at the end of the project's life? Round your answer to the nearest whole dollar.

b) What are the taxes on the sale of the equipment at the end of the project's life? Be sure to indicate clearly if taxes are owed or if there is a tax benefit. Round your answer to the nearest whole dollar.

c) What is the net cash flow for the last year of the project? Round your answer to the nearest whole dollar.
