Answer:
Dan is correct
Step-by-step explanation:
From the question, we have:
![Hours:1\ 2\ 3\ 4\ 5](https://tex.z-dn.net/?f=Hours%3A1%5C%202%5C%203%5C%204%5C%205)
Required
The average
The average hour is calculated using:
![\bar x = \frac{\sum x}{n}](https://tex.z-dn.net/?f=%5Cbar%20x%20%3D%20%5Cfrac%7B%5Csum%20x%7D%7Bn%7D)
So, we have:
![\bar x = \frac{1+2+3+4+5}{5}](https://tex.z-dn.net/?f=%5Cbar%20x%20%3D%20%5Cfrac%7B1%2B2%2B3%2B4%2B5%7D%7B5%7D)
![\bar x = \frac{15}{5}](https://tex.z-dn.net/?f=%5Cbar%20x%20%3D%20%5Cfrac%7B15%7D%7B5%7D)
![\bar x = 3](https://tex.z-dn.net/?f=%5Cbar%20x%20%3D%203)
<em>Dan calculated the mean as 3; while Bret calculated the mean as 4.</em>
<em>Hence, we can conclude that Dan s correct</em>
