Table 8E.3 presents data on the cycle time (in hours) to process small loan applications. Prepare a normal probability plot of these data. The loan agency has a promised decision time to potential customers of 24 hours. Based on the data in the table and the normal probability plot, what proportion of the customers will experience longer waiting times?
