Problem 7 The article "Aspirin Use and Survival After Diagnosis of Colorectal (Cancer" (J. of the Amer. Med. Assoc., 2009) reported that of 549 study participants who regularly Ised aspirin after being diagnosed with colorectal cancer, there were 81 colorectal cancer-specific deaths, whereas among 730 similarly diagnosed individuals who did not subseqnently use aspirin, there were 141 colorectal cancer-specific deaths. Does this data suggest that the regular use of aspirin after diagnosis will decrease the incidence rate of colorectal cancer-specific deaths? a) Formulate the null and the alternative hypotheses and test them at a = 0.02. b) Find the test p-value and confirm the result obtained in part a). c) Can it be concluded that there is a difference between the average death rate for participants that regularly use aspirins is less than the average death rate for participants that do not use the aspirin? Explain.
