Ohio Logistics manages the logistical activities for firms by matching companies that need products shipped with carriers that can provide the best rates and best service for the companies. Ohio Logistics is very concerned that it uses carriers that get their customers€™ material delivered on time, so it carefully monitors its carriers€™ on-time percentage of deliveries.
The following table contains a list of the carriers used by Ohio Logistics and the corresponding on-time percentages for the current and previous year.

a. Sort the carriers in descending order by their current year€™s on-time percentage. Which carrier is providing the best service in the current year? Which carrier is providing the worst service in the current year?
b. Calculate the change in on-time percentage from the previous to the current year for each carrier. Use Excel€™s conditional formatting to highlight the carriers whose on time percentage decreased from the previous year to the current year.
c. Use Excel€™s conditional formatting tool to create data bars for the change in on-time percentage from the previous year to the current year for each carrier calculated in part b.
d. Which carriers should Ohio Logistics try to use in the future? Why?
