In a study of 420,109 cell phone users, 115 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, altemative 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 H: p<0.00034 O B. Ho p=0.00034 H: p#0.00034 O C. Ho p> 0.00034 H,: p=0.00034 O D. Ho p+0.00034 H p=0.00034 O E. Ho p=0.00034 H p>0.00034 OF. Hai p<0.00034 H, p=0.00034 What is the test statistic? (Round to two decimal places as needed.) What is the P-value? P-value = (Round to four decimal places as needed.)

In a study of 420,109 cell phone users, 115 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, fest 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, altemative 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 H: p<0.00034 H: p+0.00034 O C. Ho p> 0.00034 O D. Ho p+0.00034 H p=0.00034 H,: p=0.00034 O E. Ho p= 0.00034 H p>0.00034 OF. Ha p<0.00034 H1: p=0.00034 What is the test statistic? (Round to two decimal places as needed.) What is the P-value? P-value = (Round to four decimal places as needed.) What is the conclusion on the null hypothesis? O A. Fail to reject the null hypothesis because the P-value is less than or equal to the significance level, a. O B. Reject the null hypothesis because the P-value is less than or equal to the significance level, a. ns O C. Fail to reject the null hypothesis because the P-value is greater than the significance level, a. O D. Reject the null hypothesis because the P-value is greater than the significance level, a. What is the final conclusion? O A. There is sufficient evidence to support 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%. O B. There is not sufficient evidence to warrant rejection of 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% O C. There is not sufficient evidence to support 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%. O D. There is sufficient evidence to warrant rejection of 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%
