QUESTION 4 A restaurant opened a website so customers can order online. They realized that the orders are coming in their website with the following cumulative probability distribution: Time between orders (min) Cumulative Probability 0.31 1 Random Numbers 1-31 32-50 51-74 75-86 87-98 99,0 0.50 0.74 0.86 0.98 1.00 By simulating the system, please select how many orders you would expect to see in one hour. Assume that there are no orders to start with and your clock starts from 0. INSTRUCTIONS: Please use the following stream of random numbers: 68,12,78.34.23, 19.49.96, 73.65, 54 46,97,91, 13, 19, 56, 68,95, 18, 14, 49,86, 75, 49. You can choose (sequentially, Le, you should first choose 68, then 12, then 78, then 34 etc.) as many numbers as you want you may not need all of them). DO NOT use Excel (or any other software) to generate random numbers and DO NOT pick your own random numbers. A. None of the above B. 12 C. 15 D. 22 QUESTION 5 Continuing on Question 4, let us now assume that the restaurant wants to predict how much time (in min) will it need for 10 orders to arrive in the website. Simulate the system again and select the correct answer INSTRUCTIONS: Please use again the following stream of random numbers: 68.12.78.34.23.19.49.96.73 65, 54, 46, 97,91, 13, 19, 56, 68,95, 18, 14, 49, 86,75. 49. You can choose (sequentially. Le you should first choose 68, then 12, then 78, then 34 etc.) as many numbers as you want you may not need all of them). DO NT use Excel (or any other software) to generate random numbers and DO NOT pick your own random numbers. A. 1.13 B. 2.19 c. 3.15 D. 4.23
