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
A box contains red and green balls. Two balls are randomly selected without replacement. The probability of selecting a red and then a green ball is 0.5. The probability of selecting a red ball in the first pick is 0.5. What is the probability of picking a green ball, given that the first ball picked was red?
A survey showed that 7575% of adults need correction (eyeglasses, contacts, surgery, etc.) for their eyesight. If 2222 adults are randomly selected, find the probability that no more thanno more than 11 of them need correction for their eyesight. Is 11 a significantly lowlow number of adults requiring eyesight correction?
Apparently, depression significantly increases the risk of developing dementia later in lift (BBC News, July 6, 2010). In a recent study it was reported that 22% of those who had depression went on to develop dementia, compared to only 17% of those who did not have depression. Suppose 10% of all people suffer from depression. What is the probability of a person developing dementia? If a person has developed dementia, what is the probability that the person suffered from depression earlier in life?
Suppose that 82% of the adult between the ages of 18 and 34 watch reality TV shows. Suppose you take a random sample of 3 persons. What is the probability that none of them watch reality TV shows? What is the probability that at least one watches reality TV shows? What is the probability 2 or more watch reality TV shows? If you were to randomly sample 1000 adults between 18 and 34 years of age in the U.S, how many of them do you expect to watch reality TV shows?
The probability that a statistics graduate from a Canadian university gets a data science job is 0.6.Ten graduates applied for executive jobs.What is the probability that exactly 3 will get jobs, at least 2 will get a job, at most 8 will get a job, and no one will get a job?
In a study of 349,212 cell phone users, it was found that 26 developed cancer of the brain or nervous system. Assuming that cell phones have no effect, there is a 0.000109 probability of a person developing cancer of the brain or nervous system. We therefore expect about 39 cases of such cancer in a group of 349,212 people. Estimate the probability of 26 or fewer cases of such cancer in a group of 349,212 people. What do these results suggest about media reports that cell phones cause cancer of the brain or nervous system? (a) P(xs 26) = (Round to four decimal places as needed.) (b) What does the result from part (a) suggest about the media reports? O A. The media reports appear to be correct because one would expect that more than 26 cell phone users would develop cancer and the study offers significant evidence to support this. B. The media reports appear to be incorrect because one would expect that more than 39 cell phone users would develop cancer. In fact, the study may offer…
A recent study reported that the prevalence of hyperlipidemia (defined as total cholesterol over 200) is 35% in children 2-6 years of age. If 10 children are analyzed, What is the probability that five are hyperlipidemic?
In a specific type of electronic card, the probability of a transistor being defective is 0.01. Let's assume there are 200 transistors on the electronic card. If there are no defective transistors, the electronic card is considered to be functioning. What is the probability of any electronic card not functioning?
The results of a nationwide Gallup poll revealed that 59.3% of people polled were in favor of the death penalty. Use the results of this Gallup poll to estimate the probability that a majority of the 12 memebers of a randomly selected jury would be in favor of the death penalty.
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.)
