In the following problem check that it is appropriate to use the normal approximation to the binomial Then use the normal distribution to estimate the requested probabilities Based on long experience an airline found that about 8 of the people making reservations on a flight from Miami to Denver do not show up for the flight Suppose the airline overbooks this flight by selling 263 ticket reservations for an airplane with only 255 seats USE SALT a What is the probability that a person holding a reservation will show up for the flight 0 92 b Let n 263 represent the number of ticket reservations Let r represent the number of people with reservations who show up for the flight What expression represents the probability that a seat will be available for everyone who shows up holding a reservation P rz 263 P r 255 P r 263 P r 255 c Use the normal approximation to the binomial distribution and part b to answer the following question What is the probability that a seat will be available for every person who shows up holding a reservation Round your answer to four decimal places

For our random sample of 24 people who dine out find the following probabilities rounded to five decimal places Recal that n 24 and p 0 33 were previously defined 1 The probability exactly 12 diners chose their restaurant based on a peer review site is P x 12

Aldrich Ames is a convicted traitor who leaked American secrets to a foreign power Yet Ames took routine lie detector tests and each time passed them How can this be done Recognizing control questions employing unusual breathing patterns biting one s tongue at the right time pressing one s toes hard to the floor and counting backwards by 7 are countermeasures that are difficult t detect but can change the results of a polygraph examinationt In fact it is reported in Professor Ford s book that after only 20 minutes of instruction by Buzz Fay a prison inmate 85 of those trained were able to pass the polygraph examination even when guilty of a crime Suppose that a random sample of five students in a psychology laboratory are told a secret and then given instructions on how to pass the polygraph examination without revealing their knowledge of the secret What are the following probabilities Round your answers to three decimal places USE SALT a All the students are able to pass the polygraph examination b More than half the students are able to pass the polygraph examination c No more than half of the students are able to pass the polygraph examination d All the students fail the polygraph examination
