Question
A government's department of transportation reported that in 2009, airline A led all domestic airlines in on-dme arfivals for domestic flights, with a rate of 0.839. Complete parts (a) through (e) below The probability is 0.1927 Round to four decimal places as needed.) b. Using the binomial distribution, what is the probability that in the next six flights, all six fights will be on time? The probability is 0.3488 Round to four decimal places as needed.) c. Using the binomial distribution, what is the probability that in the next six flights, at least four flights will be on time? The probability is 0.9431 (Round to four decimal places as needed.) d. What are the mean and standard deviation of the number of on-time arrivals? Letn 6 The mean of the number of on-time arrivals is 5.034 Round to four decimal places as needed) The standard deviation of number of on-time arrivals is 0.9003 Round to four decimal places as needed.) o. What assumption(s) do you need to make in (a) through (c)? Select all that apply A. Each observation is dassified into one of two mutually exclusive and coilectively exhaustive categories. B. The outcome of any observation s independent of the outcome of any other observation. C. The probability of an observation being classted as te event of interest, t, is costant from observation to observation. D. The outcome of any observations dependent of the outcome of any other observation.Explanation / Answer
Solution:- (A), (B), (C)
e)
(A) Each observation is classified as one of two muttually exclusive and collectively exhaustive events.
(B) The outcome of any observation is independent of the outcome of any other observation.
(C) The probability of an event being classified as the event of the interest, , is constant from observation to observation.
