Question
A recent study of the relationship between Social Activity and Education for a sample of corporate executives showed the following results.
Social Activity
Education Above Average Average Below Average
College 30 20 10
High School 20 40 90
Grade School 10 50 130
The appropriate test statistic for the analysis is a(n) _________.
A.) F statistic
B.) t statistic
C.) Z statistic
D.) Chi-square statistic
E.) Poisson statistic
Explanation / Answer
Here we are trying to judge whether there is a relationship between the two variables - Social Activity and Education. The null and the alternate hypothesis here are given as:
H0: The two variables are not associated here and are independent.
HA: The two variables are associated and not independent.
This is a case of a chi square test statistic where the expected frequencies are first computed and then the chi square test statistic is computed.
Therefore D is the correct answer here.
