According to a flight statistics website, in 2009, a certain airline had the highest percentage of on-time flights in the airlines industry, which was 81.2%. Assume this percentage still holds true for that airline. Use the normal approximation to the binomial distribution to complete parts a through c below.
c. Determine the probability that, of the next 30 flights from
this airline, 25, 26, 27, or 28 flights will arrive on
time.

According to a flight statistics website, in 2009, a certain airline had the highest percentage of on-time flights in the airlines industry, which was 82.3%. Assume this percentage still holds true for that airline. Use the normal approximation to the binomial distribution to complete parts a through c below. a. Determine the probability that, of the next 30 flights from this airline, less than 22 flights will arrive on time. P(x<22)= (Round to four decimal places as needed.)
According to the Bureau of Transportation Statistics, 81.9% of American Airlines flights were on time in 2017. Assume this percentage still holds true for American Airlines. For the next 46 flights from American Airlines, use the normal approximation to the binomial distribution to complete parts A through D. A. Determine the probability that fewer than 36 flights will arrive on time. (Round to four decimal places as needed.) B. Determine the probability that exactly 32 flights will arrive on time....
32) According to American Airlines, Flight 215 from Orlando to Los Angeles is on time 90% of the time. Randomly select 150 flights and use the normal approximation to the binomial to approximate the probability that at least 125 flights are on time 33) of all 3-to 5-year-old children, 56% are enrolled in school. If a sample of 500 such children is randomly selected, use the normal approximation to the binomial to approximate the probability that at most 200 will...

Flights American Airlines Flight 201 from New York's JFK airport to LAX airport in Los Angeles uses a Boeing 767-200 with 168 seats available for passengers. Because some people with reservations don't show up, American can overbook by accepting more than 168 reservations. If the flight is not overbooked, the airline will lose revenue due to empty seats, but if too many seats are sold and some passengers are denied seats, the airline loses money from the compensation that must...

In the airline business, "on-time" flight arrival is important for connecting flights and general customer satisfaction. Is there a difference between summer and winter average on-time flight arrivals? Let x1 be a random variable that represents percentage of on-time arrivals at major airports in the summer. Let x2 be a random variable that represents percentage of on-time arrivals at major airports in the winter. A random sample of n1 = 16 major airports showed that x1 = 74.2%, with s1...
What happened on United flight 3411?What service expectations do customers have of airlines such as United and How did these expectations develop over time? Thank You! In early April 2017, United Airlines (United), one of the largest airlines in the world, found itself yet again in the middle of a service disaster this time for forcibly dragging a passenger off an overbooked flight. The incident was to become a wake-up call for United, forcing it to ask itself what to...
A common practice of airline companies is to sell more tickets for a particular flight than there are seats on the plane, because customers who buy tickets do not always show up for the flight. Suppose that the percentage of no-shows at flight time is 2%. For a particular flight with 244 seats, a total of 250 tickets were sold. What is the probability that the airline overbooked this flight? Click here to view page 1 of the standard normal...
Case 34 Emirates Airline Emirates Airline was one of the three Middle East carriers that were singled out by the largest US airlines in the report that was released on March 5, 2015. The report charged that that the flagship airline of Dubai, along with Etihad Airways and Qatar Airways, had received over $42 billion in government subsidies and tax breaks since 2004. Claiming that this gave an unfair advantage to these state-owned airlines, the US airlines demanded that the...
