2) A company was examining the perception of sports fans in a specific region and outside of that region to see if people viewed a specific team favorable or unfavorable. It was previously determined that given a person was from the region the probability they considered the team favorable was 0.7, and given that the person was not from the region, the probability they considered the team unfavorable was 0.28. Consider a collection of 35 people were surveyed, where 28 were from the region, and 7 people were from outside the region. a) Given that a randomly selected response from the sample was favorable, what is the probability they were from the region? b) Given that a randomly selected response from the sample was not favorable, what is the probability they were from the region?
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
A survey showed that 80% of adults need correction (eyeglasses, contacts, surgery, etc) for their eyesight. If 19 adults are randomly selected find the probability that no more than 1 of them need correction for their eyesight. Is 1 significantly low number of adults requiring eyesight correction. a. The probability that no more than 1 of the 19 adults require eyesight correction is b. Is 1 significantly low number of adults requiring eyesight correction: Note that a small probability is one that is less than 0.05.
4.The mortality rate for a certain disease is 25%. A random sample of twelve patients with this disease is selected. a.What is the probability that exactly half of the patients selected will die from the disease? b.What is the probability that at least two of the twelve patients will die from the disease?
Use the data in the following table that shows results from a polygraph (lie detector) conducted by researchers Charles R. Honts and Gordon H. Barland. In each case, it was known if the subjects lied or did not lie, so the table indicates when the polygraph was correct. If two different subjects are randomly selected without replacement, find the probability that they both lied.
In a survey of consumers aged 12 and older, respondents were asked how many cell phones were in use by the household. (No two respondents were from the same household.) Among the respondents, 211answered "none,"289 said "one," 373 said "two," 143 said "three," and 138 responded with four or more. A survey respondent is selected at random. Find the probability that his/her household has four or more cell phones in use. Is it unlikely for a household to have four or more cell phones in use? Consider an event to be unlikely if its probability is less than or equal to 0.05.
