One of the early studies linking smoking and lung cancer compared patients hospitalized with lung cancer tosimilar patients without lung cancer (hospitalized for other reasons), and recorded whether each patient smoked.For a hypothesis test testing whether the proportion of smokers is higher for the patients with lung cancer thanfor patients without lung cancer, the p-value is less than 0.000001.

(1950) "Smoking and carcinoma of the lung: preliminary report", BritishMedical Journal.Whether or not we can conclude that smoking causes lung cancer depends on the statistical method theresearchers used to obtain the p-value.No, with the given p-value we would fail to reject HO in favor of HA.Yes, with the given p-value we would reject H0 in favor of HA, and conclude that smoking causes lungcancer.Based on this study we cannot conclude that smoking causes lung cancer,regardless of the p-value.

Here, the test is conducted to check whether smoking causes lung cancer. The null hypothesis will…
