Given the previous analyses based on the observed inter-arrival times between the orders and the times to process them (see the two spreadsheets provided in the previous questions), the site manager hopes to estimate the average utilization of the in-store shoppers. With 11 in-store shoppers, what is their average utilization? Note: 1. Provide your answer as a percentage, but do not include the % mark. Round your answer to 2 decimal places. For example, if your answer is 12.123%, enter 12.12. 2. Please make use of the two spreadsheets appeared in previous questions to perform the required calculations. Some of the intermediate results may already be available from earlier questions. However, please make sure that they are correct as they may affect the correctness of your answer to the current question.
