  2. The renewal process is stationary

  3. The renewal function is increasing

  4. All of the above

Show answer
Correct Option: D
Explanation:

All of the above assumptions are key to Renewal Theory.

What is the relationship between the renewal function and the renewal rate?

  1. The renewal rate is the derivative of the renewal function

  2. The renewal function is the integral of the renewal rate

  3. The renewal rate is the reciprocal of the renewal function

  4. None of the above

Show answer
Correct Option: A
Explanation:

The renewal rate is the derivative of the renewal function.

What is the probability that a renewal event occurs in a given time interval?

  1. Renewal function

  2. Renewal rate

  3. Renewal interval

  4. Renewal process

Show answer
Correct Option: A
Explanation:

The renewal function gives the probability that a renewal event occurs in a given time interval.

Which of the following is an example of a renewal process?

  1. The number of phone calls received by a call center in a day

  2. The time between arrivals of buses at a bus stop

  4. All of the above

Show answer
Correct Option: D
Explanation:

All of the above are examples of renewal processes.

What is the mean of the renewal function?

  1. The expected number of renewals in a unit time interval

  2. The expected time between two consecutive renewals

  3. The probability that a renewal event occurs in a given time interval

  4. None of the above

Show answer
Correct Option: A
Explanation:

The mean of the renewal function is the expected number of renewals in a unit time interval.

  4. None of the above

Show answer
Correct Option: A
Explanation:

The variance of the renewal function is the expected time between two consecutive renewals.
