Question
![**Text Transcription:**
Among 8345 cases of heart pacemaker malfunctions, 493 were found to be caused by firmware, which is software programmed into the device. If the firmware is tested in 3 different pacemakers randomly selected from this batch of 8345 and the entire batch is accepted if there are no failures, what is the probability that the firmware in the entire batch will be accepted? Is this procedure likely to result in the entire batch being accepted?
The probability is [____]. This procedure is [likely] to result in the entire batch being accepted. (Round to three decimal places as needed.)
**Explanation:**
The text does not contain any graphs or diagrams. It is a statistical problem involving probability calculation. The scenario describes testing a random batch of pacemakers to determine if the whole batch can be accepted based on the firmware's performance in selected units. The reader is asked to calculate this probability and determine the likelihood of the procedure's success.](https://content.bartleby.com/qna-images/question/381c88fc-86c8-43b0-81f2-55a4fcd1abcd/e5ac1b0e-02d0-4fb0-8d46-2f5c06aefc62/0vurs9_thumbnail.jpeg)

Assuming that cell phones have no effect, there is a 0.000469 probability of a person developing cancer of the brain or nervous system. We therefore expect about 167 cases of such cancer in a group of 354,079 people. Estimate the probability of 139 or fewer cases of such cancer in a group of 354,079 people. What do these results suggest about media reports that cell phones cause cancer of the brain or nervous system?
