Question

Based on histogram above what is the average number of hours worked by 20 salesperson in company G

Answer 1

`Average = 38`

Explanation:

Given

The attached histogram

Required

The average work hours by 20 salespeople

First, we get the total hours worked as follows:

`Hours = 3 * 30 + 5 * 34 + 9 * 40 + 2 * 45 + 1 * 50`

`Hours = 760`

Divide by number of salespeople

`Average = Hours/n`

`Average = 760/20`

`Average = 38`
