Draw the suitable 2x2 table, compute and interpret suitable measure of association

You suspect that association between alcohol use and CHD might be confounded by smoking. You gather the following data

	Smokers		nonsmokers
	CHD NO CHD		CHD NO CHD
alcohol use	80	40	10	20
No alcohol	20	10	40	80

Compute the suitable measure of association between alcohol use and CHD in both smokers and non-smokers. Describe whether smoking was confounder of the association. Determine the relationship of alcohol use to CHD after controlling for confounding?
