You. have a simulation model for daily sales for your chain of retail stores. From 1 prior simulations, you know that the standard deviation of the sales per day is l 182.1. You want to know the average number of sales per day with 99% ! condence and: a margin of error of 9. To obtain this, how many simulation l replications are needed? Since the number of replications must be an integer, please round up your answer to the next integg. Please use the following zscores: - zscore fora 99% C! = 2.58 - z-score for a 98% CI = 2.33 r- zscore fora 95% Cl = 1.96 . z-score fora 90% Cl = 1.64 Question 9 2 pts Acredit card transaction was fraudulent but was not flagged by the credit card analytics engine as being fraud.
