Question 867276: A survey of 1,200 men and women asked, "Do you earn over $75,000 per year?" The table below shows the responses for males and females.
Male Female Total
Income over $75,000 585 485 1,070
Income below $75,000 65 65 130
Total 650 550 1200
Based on these data, are "being female" and "earning over $75,000" independent events?

Hi
Male Female Total
Income over $75,000 585 485 1,070
Income below $75,000 65 65 130
Total 650 550 1200
Based on these data, are "being female" and "earning over $75,000" independent events?
485/1070 = .45 , 585/1070 = .55
NOT independent events, appears gender effects earning power > $75,000
