A person’s educational attainment and age group was collected by the U.S. Census Bureau in 1984 to see if age group and educational attainment are related. The counts in thousands are in table D. Do the data show that educational attainment and age are independent? Test at the 5% level. Hint: Start by calculating the row and column totals.

Table #D: Educational Attainment and Age Group

Education	Age Group					Row Total
Education	25-34	35-44	45-54	55-64	>64	Row Total
Did not complete HS	5416	5030	6250	7606	13700	38002
Competed HS	17500	1900	9500	8795	7500	45195
College 1-3 years	8600	6000	3124	2524	2500	22748
College 4 or more years	9800	7500	3904	3109	2483	26796
Column Total	41316	20430	22778	22034	26183	132741

Answer

Null hypothesis: Ho: educational attainment and age are independent

Alternate hypothesis: Ha: educational attainment and age are related

Degree of freedom =(row-1)*(column-1) =(4-1)*(5-1)=12

x²	4895.532	8336.429	664.19	1308.084	7725.393	22929.63

The chi-square for this data is thus 22929.63 and the p-value from the chi-square table is 0.0000. Since the p-value is less than alpha value; that is 0.0000 < 0.05, there is sufficient evidence to reject the null hypothesis and conclude that the educational attainment and age are related.
