A railway promises to ship freight from Toronto to Vancouver in 9 days, but customers consider any time between 6 and 14 days to be acceptable. Last week an auditor examined a sample of 71 shipments and found their delivery time had a mean of 10.4 days and a standard deviation of 1.5 days. The auditor also found 4 shipments where the customer had been charged too much money. With respect to shipping time, calculate the potential Sigma score for the process.
