Answer:
[tex]Average = 38[/tex]
Step-by-step explanation:
Given
The attached histogram
Required
The average work hours by 20 salespeople
First, we get the total hours worked as follows:
[tex]Hours = 3 * 30 + 5 * 34 + 9 * 40 + 2 * 45 + 1 * 50[/tex]
[tex]Hours = 760[/tex]
Divide by number of salespeople
[tex]Average = Hours/n[/tex]
[tex]Average = 760/20[/tex]
[tex]Average = 38[/tex]
