An article states that false-positives in polygraph tests (tests in which an individual fails even though he or she is telling the truth) are relatively common and occur about 20% of the time. Suppose that such a test is given to 10 trustworthy individuals. (Round all answers to four decimal places.) (a) What is the probability that all 10 pass? P(X = 10) = (b) What is the probability that more than 2 fail, even though all are trustworthy? P(more than 2 fail, even though all are trustworthy) = (c) The article indicated that 500 FBI agents were required to take a polygraph test. Consider the random variable x = number of the 500 tested who fail. If all 500 agents tested are trustworthy, what are the mean and standard deviation of x? Mean = Standard deviation =

A Boston College survey consisted of 320 Michigan workers who were laid off between 1979 and 1984, I found that 20% had been out of work for at least two years. Suppose you were to select another random sample of 320 workers among all employees laid off between 1979 and 1984. Which It would be the probability that your sample percentage of unemployed workers. for at least two years, differs from the percentage obtained in the survey of Boston College, 5% or more?

One interpretation of a baseball player's batting average is as the empirical probability of getting a hit each time the player goes to bat. If a player with a batting average of 0.26 bats 5 times in a game, and each at-bat is an independent event, what is the probability of the player getting at least one hit in the game? (Round your answer to 3 decimal places.)

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.)
