Answer:
6 salespersons
Step-by-step explanation:
A histogram shows the graphical representation of the distribution of numerical data using bars of different lengths.
From the histogram:
The number of salespersons who sold 11 - 12 packages = 1
The number of salespersons who sold 13 - 14 packages = 2
The number of salespersons who sold 15 - 16 packages = 3
Therefore the new agents who sold more than 10 vacation packages = 1 + 2 + 3 = 6 salespersons
