On-time arrivals, lost baggage, and customer complaints are three measures that are typically used to measure the quality of service being offered by airlines. Suppose that the following values represent the on-time arrival percentage, amount of lost baggage, and customer complaints for 10 U.S. airlines.
|
Homework Answers
a)
probability that this individual flight will have an on-time arrival =0.865 (since it has on time arrival of 86.5%)
b)
probability =3/10 =0.3 (since 3 of 10 airlines have less than two mishandled baggage reports per 1,000 )
c)
probability =5/10 =0.5 (since 5 of 10 airlines have more than one customer complaint per 1,000 passengers
d)
probability that a randomly selected AirTran Airways flight will not arrive on time =1-P(arrive on time) =1-0.871 =0.129

Suppose an article included the accompanying data on airline quality score and a ranking based on the number of passenger complaints per 100,000 passengers boarded. In the complaint ranking, a rank of 1 is best, corresponding to fewest complaints. Similarly, for the quality score, lower scores correspond to higher quality.

The time between customer arrivals at a furniture store has an approximate exponential distribution with mean θ = 8.1 minutes. [Round to 4 decimal places where necessary.] If a customer just arrived, find the probability that the next customer will arrive in the next 6 minutes. If a customer just arrived, find the probability that the next customer will arrive within next 13 to 15 minutes? If after the previous customer, no customer arrived in next 13 minutes, find the...
