A random sample of 200 married men, all retired were classified according to Education and Number of Children as detailed below: 
Number of Children 
Education 0-1 2-3 Over3 
Elementary 14 37 32 
Secondary 19 43 17 
College 22 17 10 


Test the hypothesis that at 0.05 level of significance, the size of family is independent of the level of education attained by the father. 


----
Ho: row and column factors are independent
Ha: they are not independent
----
I ran a Chi-Sq test against the 3 by 3 set of data
and got the following:
test statistic: Chi-Sq = 17.6073
p-value = 0.0015

Since the p-value is less that 5%, reject Ho.
