In a survey of U.S. adults with a sample size of 2082, 370 said Franklin Roosevelt was the best president since World War II. Two U.S. adults are selected at random from this sample without replacement. Complete parts (a) through (d).

There are declining levels of cooperation among persons contacted in surveys and this brings concerns to pollsters. A pollster contacts 92 people in the 18-21 age bracket and finds that 78 of them respond and 14 refuse to respond. When 276 people in the 22-29 age bracket are contacted, 259 respond and 17 refuse to respond. Assume that 1 of the 368 people is randomly selected. Find the probability of getting someone in the 22-29 age bracket or someone who agreed to respond. Report the answer as a percent rounded to one decimal place accuracy. You need not enter the "%" symbol. prob = Question Help: M Mes
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…
