A sample of 16 Triple-A minor league baseball teams were selected for statistical analysis. The following data show the average attendance for the 16 teams selected. Also shown are the teams’ records; W denotes the number of games won, L denotes the number of games lost, and PCT is the proportion of games played that were won.  Additionally, each teams’ major league association was given. The data are contained in the file named AAA.

1. Graph and Summary statistics:  present a graph that summarizes the data along with a table of summary statistics for each variable in the data set.  An interpretation must accompany any graph, chart, or table that you use.
2. Methods:  
   1. Develop estimated regression equations, first using attendance as the dependent variable and then using number of wins as the independent variable. Discuss your findings.
   2. Develop an estimated regression equation with attendance as dependent variable and both league and wins as the independent variables.  Discuss your findings.
   3. What is the predicted attendance for an America league AAA team with 72 wins?

A particular book publisher is thinking about starting up a new national magazine in a small town. It's thought that this publisher would have to get over 12% of the book market to be financially secure. While planning to launch this magazine, a survey was taken of a sample of 400 readers. After providing an inside look into this magazine, one question asked the participants if they would subscribe to this magazine if the cost didn't exceed $20 per month. Suppose that the number of participants that said they would subscribe is 58.

a. Can this publisher conclude that this proposed magazine will be financially feasible?

b. Suppose that the true value of the overall proportion of readers who will subscribe to this magazine is .13. Was the decision made in part a correct? If not, what type of error was made?

c. State the meaning of a type 1 and type 2 error in the content of this example. What would be the consequences of making these errors to the publisher?

Roll-on (Ltd), South Africa , is a specialist manufacturer of ‘roller door’. In seeking to expand its operations, it has the opportunity to acquire an American subsidiary company, Door Dynamics or set up a new division in South Africa. The relevant figures for these two options are as follows:

Set up new division at home (RSA)      
Costs Rands(millions)
Cost of premises 30. 400
Machinery 22. 000
Annual Sales 16. 000
Annual variable cost 5. 000
Additional head office expense 1. 000
Existing head office expenses 0. 500
Depreciation: machinery (10%) 2 .200

Acquisition (Door Dynamics)
Costs Rands(millions)
Acquire shares from existing shareholders
10. 000
Redundancy cost 2. 500
Annual Sales 18.000
Annual variable cost 9.500
Annual fixed cost 5.500
Consultation fees 5.800
Additional information:
• Project life is 10 years
• Roll-on (Ltd) current cost of capital is 12%
• Inflation in the USA is expected to be below the South African inflation by 3% per year, throughout the life of the project.(Hint: use 9% as discount rate)
• Assume the current rate of R16 to 1 USD.

Design a Ship class that has the following members:

• A member variable for the name of the ship (a string)
• A member variable for the year that the ship was built (a string)
• A constructor and appropriate accessors and mutators
• A virtual print function that displays the ship’s name and the year it was built.

Design a CruiseShip class that is derived from the Ship class. The CruiseShip class
should have the following members:

• A member variable for the maximum number of passengers (an int )
• A constructor and appropriate accessors and mutators
• A print function that overrides the print function in the base class. The CruiseShip class’s print function should display only the ship’s name and the maximum number of passengers.

Design a CargoShip class that is derived from the Ship class. The CargoShip class
should have the following members:

• A member variable for the cargo capacity in tonnage (an int ).
• A constructor and appropriate accessors and mutators.
• A print function that overrides the print function in the base class. The CargoShip class’s print function should display only the ship’s name and the ship’s cargo capacity.

After you have created these classes, create a driver program that defines an array pointers to your abstract base class Ship. It should present a menu to allow the user to enter a Cruise Ship or a Cargo Ship. When the user selects cruise ship, it should prompt them for the name, year built, and the number of passengers. When the user selects cargo ship, it should prompt them ffor the name, year built, and the maxium cargo load (in tons). Each selection should create an object that can be stored into your array of pointers. When the program exits, it should display the history of the session which includes each of the objects the user created which will be a combination of cruise ships and cargo ships. An example output is shown here:

Menu

1. Cruise Ship
2. Cargo Ship

An author argues that more​ American-born baseball players have birth dates in the months immediately following July 31 because that was the age cutoff date for nonschool baseball leagues. The table below lists months of births for a sample of​ American-born baseball players and​ foreign-born baseball players. Using a 0.01 significance​ level, is there sufficient evidence to warrant rejection of the claim that months of births of baseball players are independent of whether they are born in​ America? Do the data appear to support the​ author's claim? Jan. Feb. March April May June July Aug. Sept. Oct. Nov. Dec.
