Correct! False True TRUE or FALSE? Simulation can be used to study detailed relations that might be lost in an analytical or numerical treatment, but it might be very time consuming/costly. pts Question 1 Correct! False True TRUE or FALSE? In a single -server queue simulation, if the arrival rate of customers showing up is many times higher than the service rate of the single -server, then a queue will not be formed. pts Question 2 pts Question 3 8/3/2020 ISyE 6644 - Summer 2020 - Midterm Test 1: Simulation and Modeling for Engineering and Science - ISYE -6644 -OAN/O01 https://gatech.instructure.com/courses/128642/quizzes/128199?module_item_id=751192 2/21 TRUE or FALSE? Suppose the arrival of clients to a bank can be modeled as a Poisson process with a given hourly rate . Then the expected number of clients arriving between 10:00 -11:00am is the same as the expected number of clients arriving between 1:00 -2:00pm. Correct! True False Correct! False True TRUE or FALSE? If the covariance of and is equal to zero, i.e. , then and must be independent . pts Question 4 Correct! False True This question has been regraded. TRUE or FALSE? Suppose I toss two fair dice. The events "sum is less or equal than 2" and "sum is greater than 11" are independent.

Suppose a pen is drawn at random from the pack, is replaced, and then the process repeated one more time (for a total of two draws). What is the probability of first drawing a blue pen and then a green pen? pts Question 6 Correct! e. 1/7 d. 2/7 c. 11/14 b. 4/7 a. 3/4 Again, suppose a pack contains 4 blue, 2 red and 2 green pens. A pen is drawn at random from the pack, but this time the pen is not replaced, and then the process is repeated one more time (for a total of two draws). What is the probability of first drawing a blue pen and then a red pen? pts Question 7The benefits of buying summaries with Stuvia:
