Chapter 5, Problem 1P

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.

Chapter 5, Problem 1P, On-time arrivals, lost baggage, and customer complaints are three measures that are typically used

  1. a. Based on the data above, if you randomly choose a Delta Air Lines flight, what is the probability that this individual flight will have an on-time arrival?
  2. b. If you randomly choose 1 of the 10 airlines for a follow-up study on airline quality ratings, what is the probability that you will choose an airline with less than two mishandled baggage reports per 1,000 passengers?
  3. c. If you randomly choose 1 of the 10 airlines for a follow-up study on airline quality ratings, what is the probability that you will choose an airline with more than one customer complaint per 1,000 passengers?
  4. d. What is the probability that a randomly selected AirTran Airways flight will not arrive on time?

To determine

Find the probability that a randomly selected D flight has an on-time arrival.

Answer to Problem 1P

The probability that a randomly selected D flight has an on-time arrival is 0.865.

Explanation of Solution

Calculation:

From the given table, the percentage of D flight has an on-time arrival is 86.5%.

Thus, the probability that a randomly selected D flight has an on-time arrival is 0.865.

Find the probability that a randomly selected airline has less than two mishandled baggage reports per 1,000 passengers.

Answer to Problem 1P

The probability that a randomly selected airline has less than two mishandled baggage reports per 1,000 passengers is 0.3.

Explanation of Solution

Calculation:

From the given table, there are 3 airlines which have less than two mishandled baggage reports per 1,000 passengers. Also, there are 10 airlines.

Define the event A as the airline has less than two mishandled baggage reports per 1,000 passengers.

The required probability is obtained as given below:

P(A)=(Number of airlines less than two mishandled baggage reports per 1,000 passengers)Total number of airlines=310=0.3

Thus, the probability that a randomly selected airline has less than two mishandled baggage reports per 1,000 passengers is 0.3.

To determine

Find the probability that a randomly selected airline has more than one customer compliant per 1,000 passengers.

Answer to Problem 1P

The probability that a randomly selected airline has more than one customer compliant per 1,000 passengers is 0.5.

Explanation of Solution

Calculation:

From the given table, there are 5 airlines which have more than one customer compliant.

Define the event B as the airline that has more than one customer compliant per 1,000 passengers.

The required probability is obtained as given below:

P(B)=(Number of airlines that has more than one customer compliant per 1,000 passengers)Total number of airlines=510=0.5

Thus, the probability that a randomly selected airline has more than one customer compliant per 1,000 passengers is 0.5.

To determine

Find the probability that a randomly selected AT flight does not have an on-time arrival.

Answer to Problem 1P

The probability that a randomly selected AT flight does not have an on-time arrival is 0.129.

Explanation of Solution

Calculation:

From the given table, the percentage of AT flight has an on-time arrival is 87.1%.

Define the event C as AT flight has an on-time arrival.

The required probability is obtained as given below:

P(CC)=1P(C)=10.871=0.129

Thus, the probability that a randomly selected AT flight does not have an on-time arrival is 0.129.

Suppose the Internal Revenue Service reported that the mean tax refund for the year 2022 was $3401. Assume the standard deviation is $82.5 and that the amounts refunded follow a normal probability distribution. Solve the following three parts? (For the answer to question 14, 15, and 16, start with making a bell curve. Identify on the bell curve where is mean, X, and area(s) to be determined. 1.What percent of the refunds are more than $3,500? 2. What percent of the refunds are more than $3500 but less than $3579? 3. What percent of the refunds are more than $3325 but less than $3579?
A normal distribution has a mean of 50 and a standard deviation of 4. Solve the following three parts? 1. Compute the probability of a value between 44.0 and 55.0. (The question requires finding probability value between 44 and 55. Solve it in 3 steps. In the first step, use the above formula and x = 44, calculate probability value. In the second step repeat the first step with the only difference that x=55. In the third step, subtract the answer of the first part from the answer of the second part.) 2. Compute the probability of a value greater than 55.0. Use the same formula, x=55 and subtract the answer from 1. 3. Compute the probability of a value between 52.0 and 55.0. (The question requires finding probability value between 52 and 55. Solve it in 3 steps. In the first step, use the above formula and x = 52, calculate probability value. In the second step repeat the first step with the only difference that x=55. In the third step, subtract the answer of the first part from the…
