The​ no-show rate for an​ airline's reservations is 16​%. In other​ words, the probability is 0.16 that a person making a reservation will not take the flight. For the next​ flight, 46 people have reservations. Use the normal approximation to the binomial to approximate the following probabilities.

a. What is the probability that exactly 6 people do not take the​ flight?

​P(X = 6​) =

Based on long experience, an airline found that about 4% 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 268 ticket reservations for an airplane with only 255 seats. (Round your answers to four decimal places.) (a) What is the probability that a person holding a reservation will show up for the flight?(b) Let n = 268 represent the number of ticket...

Sam 'Vandelay' Johnson plays basketball for his college team. You've observed that the probability of Sam making a given shot is 0.6 and that the success of a given shot is independent of other shots. Over the course of many games, Sam takes 80 attempted shots at the basket. Let W be the random variable that is the number of successful shots. You should use the normal approximation to the binomial to calculate the probabilities in parts b) and c)....

Assume that the octane level of mid-grade gasoline has a normal distribution with a mean of 89.15 and a standard deviation of 0.16. We take many samples of this gasoline and measure their octane levels. Problem 1: What proportion of the samples will have octane levels higher than 89.50? Solution: Let XX denote the octane level, which is normal with μ=89.15μ=89.15 and σ=0.16σ=0.16. We need to find the probability that XX is greater than 89.5089.50. P(X>89.50)=P(X−μσ>89.50−89.150.16)=P(Z>2.19)P(X>89.50)=P(X−μσ>89.50−89.150.16)=P(Z>2.19) Many normal probability tables...

A biased coin (one that is not evenly balanced) is tossed 6 times. The probability of Heads on any toss is 0.3. Let X denote the number of Heads that come up. 1. Does this experiment meet the requirements to be considered a Bernoulli Trial? Explain why or why not. 2. If we call Heads a success, what would be the parameters of the binomial distribution of X? (Translation: find the values of n and p) 3. What is the...

Problem 4) In 2012, the percent of American adults who owned cell phones and used their cell phone to send or receive text messages was at an all-time high of 80%. Assume that 80% refers to the population parameter π. More recently in 2016, a polling firm contacts a simple random sample of 110 people chosen from the population of cell phone owners. The firm asks each person “do you use your cell phone to send or receive texts? Yes...
