	Children	No Children
Lowest 25% Income	24	35
Middle 50% Income	14	21
Top 25% Income	28	24

What is the chi-square test-statistic and the corresponding p-value for this data at the 0.05 significance level?

χ2 =
	[three decimal accuracy]

p-value =
	[three decimal accuracy]

Test Conclusion:

Reject H0H0: There is enough evidence to suggest that income level and having children are dependent.
Fail to Reject H0H0: There is not enough evidence to suggest that income level and having children are dependent.
