Assignment
Consider a study in which people were recruited and followed for 40 years to determine their health problems. The researchers were interested in lung cancer, so at the end of the study they counted the number of participants who had died from lung cancer, or currently had it, and those that did not. They also counted how many were nonsmokers their whole life or had been smokers at some point in their lives. The number of nonsmokers with lung cancer was 36 and the number of nonsmokers with no sign of lung cancer was 815. The number of smokers with lung cancer was 26 and the number of smokers with no sign of lung cancer was 161.
Determine whether there appears to be a statistically significant relationship between smoking and risk of lung cancer, we would conduct a χ2 analysis. When performing this analysis, which of the values below is closest to the χ2 statistic we would obtain?
