The following table contains data from study of two airlines which fly to small Town, USA. Number of flights which were on time Number of flights which were late Podunk Airlines 33 6 Upstate Airlines 43 5 Of one of 87 flights is randomly selected, find the probability that the flight selected is an upstate Airline flight or it is a Flight which was late? -62% -76% -13% -40%
According to flightstats.com, American Airlines flights from Dallas to Chicago are on time 80% of the time. Suppose 15 flights are randomly selected, and the number of on-time flights is recorded.Explain why this is a binomial experiment.Find and interpret the probability that exactly 10 flights are on time.Find and interpret the probability that exactly 8 flights are on time.Find and interpret the probability that exactly 5 flights are on time.
please show all work Question 7 (8 points) The following table contains data from a study of two airlines which fly to Small Town, USA. #flights on time 33 #flights late Podunk Airlines Upstate Airlines 6 43 5 a. (1 pt.) If one of the flights is randomly selected, what is the probability that the flight is an Upstate Airline, given that it is late? b. (4 pts.) If one of the flights is randomly selected, what is the probability...
2. Assume that a study of 423 randomly selected school bus routes showed that 408 arrived on time. Considering an event to be "unusual" if its probability is less than or equal to 0.05,is it "unusual" for a school bus to arrive late? Please show some work.
Consumer Reports rated airlines and found that 89% of the flights involved in the study arrived on time (i.e., within 15 minutes of scheduled arrival time). Assuming that the on-time arrival rate is representative of the entire commercial airline industry, consider a random sample of 218 flights. (Round your answers to two decimal places.) A) What is the expected number that will arrive on time? B) What is the standard deviation of this distribution?
United Airlines' flights from Denver to Atlanta are on time 50 % of the time. Suppose 10 flights are randomly selected, and the number on-time flights is recorded. Round answers to 3 significant figures. The probability that at most 3 flights are on time is?
Consumer Reports rated airlines and found that 72% of the flights involved in the study arrived on time (le, within 15 minutes of scheduled arrival time). Assuming that the on-time arrival rate is representative of the entire commercial airline industry, consider a random sample of 186 flights. (Round your answers to two decimal places.) What is the expected number that will arrive on time? 133.82 What is the standard deviation of this distribution? 5.4 Need Help? Read
The airline industry defines an on-time flight as one that arrives within 15 minutes of its scheduled time. The following table shows the number of on-time and late flights leaving New York and arriving in Miami between November 1 and December 31, 2018, by airlines: Airlines On-Time Late Total United 254 72 326 Delta 292 65 357 American 235 58 683 Total 781 195 a. What is the probability that a randomly selected flight was Delta and was late? b. ...
4. American Airlines flights from Dallas to Chicago are on time 80% of the time. Suppose 15 flights are randomly selected, and the number of on-time flights is recorded. a. Is this a binomial experiment? Explain. b. Find the probability that exactly 10 flights are on time. c. Find the probability that fewer than 10 flights are on time. d. Find the probability that at least 10 flights are on time. e. Find the mean and the standard deviation of...
A certain flight arrives on time 82 percent of the time. Suppose 134 flights are randomly selected. Use the normal approximation to the binomial to approximate the probability that (a) exactly 105 flights are on time. (b) at least 105 flights are on time. (c) fewer than 103 flights are on time. (d) between 103 and 111, inclusive are on time.
