Excel Tаsk 9 (mаx 7 pts) Gо tо the "Restаurants" sheet оf the exam file. Management is concerned that some of our regional managers might be overworked. They want to know how many restaurants each regional manager oversees. Create a pivot table that lists all the regional managers (one per row) and shows the total number of restaurants that person manages. Sort the pivot table so that the manager with the most restaurants is at the top of the pivot table. Name the pivot table's sheet as "Pivot-Managers" NOTES: Be careful -- we're asking for the Regional Manager, not the local manager. This task will be graded manually, based on our evaluation of the XLSX file you submit.
