A study of 420,057 cell phone users found that 134 of them developed cancer of the brain or nervous system Prior to this study of cell phone use, the rate of such cancer was found to be 0.0318% for those not using cell phones. Complete a. Use the sample data to construct a 90% confidence interval estimate of the percentage of cell phone users who develop cancer of the brain or nervous system (Round to three decimal places as needed.) b. Do cell phone users appear to have a rate of cancer of the brain or nervous system that is different from the rate of such cancer among those not using cell phones? Why or why not? O A. Yes, because 0 0318% is included in the confidence interval O B. No, because 0.0318% is indluded in the confidence interval OC. Yes, because 0.0318% is not included in the confidence interval O D. No, because 0.0318% is not included in the confidence interval.
