(2) Why (explain your justification for using that test)?
(3) As appropriate for the data and the test, label your dependent variables, independent variables and factors (if present). (This one only applies to some kinds of tests!)
Scenario 1: A professor always gives his students two midterm exams, each out of 100 points. He wants to know if student performance on exams improves over the course of the semester.
Scenario 2: Another professor also gives two midterm exams over the semester. She wants to know if student performance on the final exam can be predicted from performance on the two midterm exams.
Scenario 3: An ice cream shop wants to compare men and women in terms of preference for eating their ice cream out of a cone or a bowl to determine if there is a gender difference. They take a sample of 500 customers (240 men and 260 women) and ask if they prefer cones over bowls. They found that 124 men preferred cones and 90 women preferred cones. Is there a gender difference in cone preference?
Scenario 4: Three professors were each teaching one section of a course. They all gave the same final exam and they want to know if there are statistical differences between how their students do on the exam.

Write a python program that loops, prompting the user for their full name, their exam result (an integer between 1 and 100), and then writes that data out to file called ‘customers.txt’. The program should check inputs for validity according to the following rules:
The file should record each customers information on a single line and the output file should have the following appearance.
Nurke Fred 58
Cranium Richard 97
Write a second program that opens the ‘customers.txt’ file for reading and then reads each record, splitting it into its component fields and checking each field for validity.
The rules for validity are as in your first program, with the addition of a rule that specifies that each record must contain exactly 3 fields.
Your program should print out each valid record it reads.
The program should be able to raise an exception on invalid input, print out an error message with the line and what the error was, and continue running properly on the next line(s).
You need to develop the system by completing the following three tasks:
Task 1 -
Draw flowchart/s that present the steps of the algorithm required to perform the tasks specified.
Task 2 -
Select at least six sets of test data that will demonstrate the 'normal' operation of your program; that is, test data that will demonstrate what happens when a VALID input is entered.

Currently, Katie White (retail customers manager) and Jules De Martino (corporate customers manager) have their performance assessed based on how much profit/loss is made with their customers' loans and savings activities, but this has led to many disagreements. Based on figures from the previous year, the corporate customers' loans and savings activities have generated a profit of $124 million whereas the retail customers' loans and savings activities have generated a loss of $84 million. Jules is very happy with this outcome, but Katie argues Jules is lending money from her retail customers to his corporate customers.

RRB board is discussing implementing fund transfer pricing (FTP) for addressing Katie’s concern about her customers funding Jules’ activities. However, Jules argues implementing an arbitrary FTP rate will make the retail and customer managers performance evaluation too subjective. There has been some discussion in RRB board regarding implementing a Balanced Scorecard (BSC).
Required
a) Based on the figures from the previous year, what would be the adjusted profit/loss with retail customers and corporate customers if RRB set an FTP rate of 8% and which manager would benefit from this decision and why? (FTP2, 10 marks)
