11 What is the test statistics

In a study of 420,144 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 0.001 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. Which of the following is the hypothesis test to be conducted? O A. Ho P > 0.00034 O B. Ho: p #0.00034 H1 p=0.00034 H1: p= 0.00034 C. Ho p=0.00034 O D. Ho p= 0.00034 H1 p #0.00034 H1: p 0 00034 Hit p=0.00034 What is the test statistic? Z = ary (Round to two decimal places as needed.)
