Click the icon to view the data tables. a) Use z-scores to combine the three measures. Calculate the z-scores for each measurement for all three countries. A B C Procedures (#) Time (Days) Cost (%) (Round to two decimal places as needed.) b) Which country has the best environment after combining the three measures? Be careful-a lower rank indicates a better environment to start up a business.
