Among 9318 cases of heart pacemaker malfunctions, 393 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 batchof 9318 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 isV to result in the entire batch being accepted.(Round to three decimal places as needed.)

Given data: Total cases = 9318 393 = caused by firmware 3 = Different firmware selected randomly To…

In a study of 354,079 cell phone users, it was found that 139 developed cancer of the brain or nervous system. 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? (a) P(x s139) = | (Round to four decimal places as needed.) %3D

Among 6464 cases of heart pacemaker malfunctions, 341 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 6464 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 0.850 . This procedure is likely to result in the entire batch being accepted.
In a study of 213,270 cell phone users, it was found that 77 developed cancer of the brain or nervous system. Assuming that cell phones have no effect, there is a 0.000397 probability of a person developing cancer of the brain or nervous system. We therefore expect about 85 cases of such cancer in a group of 213,270 people. Estimate the probability of 77 or fewer cases of such cancer in a group of 213,270 people. What do these results suggest about media reports that cell phones cause cancer of the brain or nervous system? (a) P(x ≤ 77) = (Round to four decimal places as needed.)
Of a random sample of 100 college students, 35 expected to achieve a higher standard of living than their parents, 43 expected a lower standard of living, and 22 expected about the same standard of living as their parents. Do these data present strong evidence that, for the population of students, more expect a lower standard of living compared with their parents than expect a higher standard of living?
A survey showed that 79% of adults need correction (eyeglasses, contacts, surgery, etc.) for their eyesight. If 15 adults are randomly selected, find the probability that at least 14 of them need correction for their eyesight. Is 14 a significantly high number of adults requiring eyesight correction? The probability that at least 14 of the 15 adults require eyesight correction is nothing. (Round to three decimal places as needed.)
Among 8509 cases of heart pacemaker malfunctions, 439 were found to be caused by firmware, which is software programmed into the device.
