The mean area of homes in a certain city built in 2009 was 2438 square feet. Assume that a simple random sample of 11 homes in the same city in 2010 had a mean area of 2,295 squarefeet, with a deviation of 225 square feet. An insurance company wants to know if the mean area of homes built in 2010 is less than that of homes built in 2009.

1. Sources of monopoly power
A monopolist, unlike a competitive firm, has some market power. It can raise its price, within limits, without the quantity demanded falling to zero. The main way it retains its market power is through barriers to entry—that is, other companies cannot enter the market to create competition in that particular industry.
Complete the following table by indicating which barrier to entry appropriately explains why a monopoly exists in each scenario.
|
Scenario |
Barriers to Entry |

|---|---|---|---|---|

Exclusive Ownership of a Key Resource |
Government-Created Monopolies |
Economies of Scale |

| The Aluminum Company of America (Alcoa) formerly controlled all U.S. sources of bauxite, a key component in the production of aluminum. Given that Alcoa did not sell bauxite to any other companies, Alcoa was a monopolist in the U.S. aluminum industry from the late 19th century until the 1940s. | ||||

| In the natural gas industry, low average total costs are obtained only through large-scale production. In other words, the initial cost of setting up all the necessary pipes and hoses makes it risky and, most likely, unprofitable for competitors to enter the market. | ||||

You are tasked with estimating the cost of capital for a firm. The risk-free rate is 3.2%, the expected rate of return on the market is 17.9%. Now, another similar company (similar unlevered cost of capital) has a debt-to-equity ratio of 1 to 5. It has a debt beta near zero and an equity market-beta of 1.1. Your own firm has more debt, for a debt-to-equity ratio of 1 to 1, with a debt beta of 0.5. What is a good estimate for your equity cost of capital?

The purpose of this homework is to test your knowledge of GUI. Consider a fictional park where the entry price for 1 adult ticket is $50, and for 1 children ticket is $25. Write a simple GUI application that let user to enter the number of tickets and display the total price. The GUI should contain:
● One text field for the user to enter the number of adult tickets
● One text field for the user to enter the number of children tickets
● One button “Calculate total cost”
● One text field to display the total cost When the user clicks the button then the correct cost is displayed in the total price field. If the input text field is empty then it should be treated as 0 tickets.
