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 brainor nervous system. We therefore expect about 85 cases of such cancer in a group of 213,270 people. Estimate theprobability of 77 or fewer cases of such cancer in a group of 213,270 people. What do these results suggest aboutmedia reports that cell phones cause cancer of the brain or nervous system?(a) P(x ≤ 77) = (Round to four decimal places as needed.)

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.

A recent survey of 1030 U.S. adults selected at random showed that 627 consider the occupation of firefighter to have very great prestige. Estimate the probability (to the nearest hundredth) that a U.S. adult selected at random thinks the occupation of firefighter has very great prestige.
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?
According to Johns Hopkins data, the mortality rate of Covid-19 for the USA and the UK respectively 1.7% and 2.7%.It is expected that next week there will be 1,200,000 (1.2 million) and 238,000 Covid-19 cases for the US and the UK, respectively.Deaths in the USA and the UK assuming independent, Covid-19 for US and UK next week Find the probability that the total number of deaths is at least 27,000.Hint: Use the normal approximation to the binomial distribution.
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?
In a study of 235,722 cell phone users, it was found that 109 developed cancer of the brain or nervous system. Assuming that cell phones have no effect, there is a 0.000477 probability of a person developing cancer of the brain or nervous system. We therefore expect about 113 cases of such cancer in a group of 235,722 people. Estimate the probability of 109 or fewer cases of such cancer in a group of 235,722 people. What do these results suggest about media reports that cell phones cause cancer of the brain or nervous system? (a) P(x ≤ 109) = (Round to four decimal places as needed.)
