Question

Here is data from a study on second-hand smoke and lung cancer: Ten thousand (10,000) people
that have lived with smokers for at least 10 years were studied. Seven hundred and forty (740) of
these people got lung cancer. Therefore, 7.4% of these people got lung cancer. Their conclusion is
second-hand smoke causes lung cancer. Do you agree or disagree with their conclusion? Explain
your answer by using ONLY the data provided in this question.

Answer 1

Answer:

I disagree

Explanation:

The data doesn't give enough info, were the people who lived with smokers, smokers as well? or were they clean off nicotine.  Also the data presents itself stating the fact that second hand smoke will defiantly cause Lung cancer when in reality (as the data shows with only 7.4%) only a small percentage is affected by the smoke.
