In a study of 420,051 cell phoneusers, 142 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. Thatis, test the claim that cell phone users develop cancer of the brain or nervous system at a rate that is different from the rate of0.0340% for people who do not use cell phones. Because this issue has such greatimportance, use a 0.001 significance level. Identify the nullhypothesis, alternativehypothesis, teststatistic, P-value, conclusion about the nullhypothesis, and final conclusion that addresses the original claim. Use theP-value method and the normal distribution as an approximation to the binomial distribution.

What is the teststatistic? (round two decimal places)

What is theP-value? (round three decimal places)

What is the conclusion on the nullhypothesis?

What is the finalconclusion?
