The following is a two by two table that summarizes the data

The following is a two by two table that summarizes the data we got from a case-control study. The two key variables are smoking (yes, no) and lung cancer (yes, no). Lung Cancer Y N Y 250 200 Smoking N 100 350 Calculate the lower limit for a 95% confidence interval for the odds ratio of lung cancer comparing smokers to non- smokers? Round your answers to 2 decimals. Please use the following formula for the approximated standard error of the estimated log odds ratio: 1 n12 1 n21 1 1 + + + V n11 22
