With 11 in-store shoppers working in the Walmart Supercentre. currently there is enough capacity to process all customer orders. Nevertheless, customers still complain about long waiting times, especially on weekends. The site manager hopes to reduce the average waiting time experienced by customers. As a first step, she would like to analyze the patterns of order arrivals and the times required to process the orders (which includes the time for picking items and time for checkout and moving to the staging area). The manager examined 25 consecutive orders received on a Saturday afternoon and calculated the inter-arrival time between every two orders. The 24 inter arrival times are included in this spreadsheet. Based on the data, what should be her estimate of the average number of orders to arrive for a duration of 20 minutes? Note: 1. Round your answer to 2 decimal places. 2. You do not need to fit a distribution. Instead, your calculation of the arrival rate should be based on the sample average of the interarrival times. Your Answer: 5.28 Antir With the inter-arrival times calculated from the 25 orders, what is the coefficient of variation of the inter-arrival times? Note: 1. Round your answer to 2 decimal places. 2. Please use the same this spreadsheet as in the previous question to get the inter- arrival times. 3. Sample standard deviation should be used to calculate the coefficient of variation Your Answer: + Answer Page 1 of 3 Previous Page Next Page do Clipboard Font 1. 2.8 terarrival_times_(minutes) 2.8 6.4 3.5 0.1 1.5 3.3 0.8 7.1 0.8 1.2 0.1 12.8 8.1 3.7 3.6 8.1 4.1 0.7 2.7 5.2 3.3 0.5 0.6 10 Sheet1
