The National Football League (NFL) records a variety of performance data for individuals and teams. To investigate the importance of passing on the percentage of games won by a team, the following data show the average number of passing yards per attempt (Yards/Attempt) and the percentage of games won (WinPct) for a random sample of 10 NFL teams for the 2011 season.†

A) For the 2011 season, suppose the average number of passing yards per attempt for a certain NFL team was 6.4. Use the estimated regression equation developed in part (c) to predict the percentage of games won by that NFL team. (Note: For the 2011 season, suppose this NFL team's record was 8 wins and 8 losses. Round your answer to the nearest integer.)

B) For the 2011 season, suppose the average number of passing yards per attempt for a certain NFL team was 6.4. Use the estimated regression equation developed in part (c) to predict the percentage of games won by that NFL team. (Note: For the 2011 season, suppose this NFL team's record was 8 wins and 8 losses. Round your answer to the nearest integer.)

A Corporation receives 120 applications for positions from recent college graduates in POLS. Assume that 40% of these applicants are graduated from MIT. If they randomly select two application. What is the probability that one of them is MIT graduate?

Phyton Login program

To start the program each day the manager must login. The main (manager) window will appear with a login, create password, and cancel button. A password must exist for the login button to be enabled. The password is created in a separate window and must be 9 characters or more, and it must have at least on digit, uppercase and lowercase letter. The program will continue to show error messages and prompt for a password until a valid password is created. The valid password will be stored in a file for validation on login.
When a valid password has been created or on subsequent program runs, the main window “Create Account” button for the manager will be disabled. When the login button is clicked, the main window will change (morph) to add a login entry box.

Create the “Account Creation / Login” interface and the functions using a class for the GUI in a separate module (file) and begin the design for user name and password file handling. The window is launched when the “Create Account” button is clicked. Use the <enter> key to obtain the user entry.
Design and develop the functionality for changing the window or creating a new one to obtain a user name and password including input validation. Create an error dialog that echoes the password, and create the password validation function which must test for length (9 characters or more), an uppercase and lowercase letter, and a digit. The window must contain instructions and operating “Cancel” and “Create Account” buttons.

When the “Ok” button in the “Password Accepted” dialog is clicked the Account Creation dialog should be destroyed and the main window will now have the “Create Account” button disabled. Store the user name and password for future checking. The user should login next.
Hint: The call to the login function may not be able to be handled directly through the “command=” option of the button. A call to a function within the main GUI (outside the main loop) may need to be called which then calls the login function in the separate module.

Add the code to the login function to accept the password when the <Enter> key is pressed by binding the entry widget to a function call that tests for a match with the stored password by calling a “verify” function. The entry widget should accept input left aligned in the text box. If the entered password and stored password don’t match, alert the user and the text box should be cleared like the account creation example- entry.delete(0, END). Login operations can be done on the main window as shown here or in a separate window. Consider how the user and manager would like to interface with your program.

Java

It would be nice if you use many Functions.

1. rite a method, besides main(), which will calculate the lowest common multiple (LCM) of two numbers. For example, the multiples of 4 are 4, 8, 12, 16, 20, 24 …, and the multiples of 6 are 6, 12, 18, 24 …. The LCM is 12.
2. Do NOT use any code from the Internet!
3. Here are some more examples:
   3:5 LCM is 15
   4:8 LCM is 8
   5:7 LCM is 35
4. Your method will take two parameters, and return the LCM for those numbers.
5. Demonstrate your function is working by finding the LCM for 16:20 and 13:17

Tabulation Corporation manufactures and sells two types of electronic calculators: EL-520 W and EL-620 T. The following data was gathered from last month’s activities:

                                                                                  EL-520 W          EL-620 T

Selling price per unit                                                   $50                  $100

Variable production costs per unit                               $10                  $26

Traceable fixed production costs                                 $100,000          $150,000

Variable selling expenses per unit                                $5                    $6

Traceable fixed selling expenses                                  $5,000              $7,500

Required:

1. Prepare a segmented income statement in the contribution format for last month, showing both "Amount" and "Percent" columns for the company as a whole and for each model.
2. Why might it be very difficult to calculate separate break-even sales for each model?
3. Refer to the original data and, if necessary, the results of the segmented income statement prepared in part (1) above. Calculate the total break-even sales (in both units AND dollars) for last month, assuming that none of the fixed production costs and fixed selling expenses is traceable. Allocate the total break-even sales between the two models.
4. Again, refer to the original data and, if necessary, the results of the segmented income statement prepared in part (1) above. Calculate the total break-even sales (in both units AND dollars) for last month, assuming that the "allocated" amounts of the company's administrative expenses are actually traceable. Allocate the total break-even sales between the two models.
5. How reasonable are the total break-even sales numbers calculated in parts (3) and (4) given the actual results for last month?

Last Tuesday, Fuzzy Button Clothing Company lost a portion of its planning and finacial data when its server and its backup server crashed. The company's CFO remembers that the internal rate of return (IRR) of Project Delta is 14.6%, but he can't recall how much Fuzzy Button originally invested in the project nor the project's net present value (NPV). However, he found a note that contained the annual net cash flows expected to be generated by Project Delta. They are:

The CFO has asked you to compute project Delta's initial investment using the information currently avaliable to you. He has offered the following suggestions and observations:

A project's IRR represents the return the project would generate when its NPV is zero or the discounted value of its cash inflows equals the discounted value of its cash outflows - when the cash outflows are discounted using the project's IRR.

The level of risk exhibited by Project Delta is the same as that exhibit by the company's average project, which means that Project Delta's net cash flows can be discounted using Fuzzy Button's 9% WACC.

Given the data and hints, Project Delta's initial investment is ____________ (a. $7,746,571, b. $8,634,704, c. $7,413,064, d. $7,524,980) and its NPV is _____________(a. $919,523, b. $1,226,030, c. $1,021,692, d. $868,438) (rounded to the nearest whole dollar)

A projects IRR will __________ (a. increase, b. decrease, c. stay the same) if the project's cash inflows decrease, and everything else is unaffected.

Last Tuesday, Green Caterpillar Garden Supplies Inc. lost a portion of its planning and financial data when both its main and its backup servers crashed. The company’s CFO remembers that the internal rate of return (IRR) of Project Gamma is 13.2%, but he can’t recall how much Green Caterpillar originally invested in the project nor the project’s net present value (NPV). However, he found a note that detailed the annual net cash flows expected to be generated by Project Gamma. They are:

The CFO has asked you to compute Project Gamma’s initial investment using the information currently available to you. He has offered the following suggestions and observations:

Given the data and hints, Project Gamma’s initial investment is _________ , and its NPV is ____________ (rounded to the nearest whole dollar).

A project’s IRR will _________ if the project’s cash inflows decrease, and everything else is unaffected.
