Given below are the responses of 200 students to the questions: Do you think your self-esteem has risen since coming to college? & Are you (or do you think you are) overweight or about right or underweight?

---------------------Yes----------31-------------------89-------------------16-----------------136
--------------------Total----------55-----------------124-------------------21-----------------200
Is there a relationship between self-esteem and weight perception?
Explanation / Answer
Here we are given 3 X 2 table. And we are interested in finding the relationship between self -esteem and weight perception.
The hypothesis are
H0 : There is no relationship between self -esteem and weight perception.
H1: There is relationship between self -esteem and weight perception.
Type of response variable is categorical.
Hence we use Chi-square test of independence.
The correct number of test is 8.
