Question

In a study of 420,082 cell phone​ users, 123 subjects developed cancer of the brain or nervous system. Test the claim of a somewhat common belief that such cancers are affected by cell phone use. That​ is, test the claim that cell phone users develop cancer of the brain or nervous system at a rate that is different from the rate of​0.0340% for people who do not use cell phones. Because this issue has such great​ importance, use a 0.005 significance level. Identify the null​ hypothesis, alternative​hypothesis, test​ statistic, P-value, conclusion about the null​ hypothesis, and final conclusion that addresses the original claim. Use the​ P-value method and the normal distribution as an approximation to the binomial distribution. What is the test statistic? What is the P Value ?

Answer 1

Conclusion: We cannot conclude that cell phone users develop cancer of the brain or nervous system at a rate that is different from the rate of​ 0.0340% for people who do not use cell phones.
