In a large sample survey of an examination (say GATE!), 3,140 Students gave
‘Yes’ or ‘No’ answers to each of the first two questions in the question
paper. The following information was extracted from the answer papers.
No. of students answering
Yes No
Question 1 1,738 1,402
Question 2 1,675 1,465
Analyze the above data to understand whether the answers to Question 1 are
related to those of Question 2. How to extract information about the number
of students fell into each of four categories answering the two questions
respectively by Yes/Yes, Yes/No, No/Yes and No/No? Construct a suitable
mathematical model for the above situation and discuss the feasibility of
solution.
