Answer:
Given data :
- 3 ,6 ,6 ,7 ,8 ,11 ,15 ,16
Data is already in ascending order so let's start answering.
We have to find the mean of Given data
![\sf \: Mean = \frac{sum \: of \: all \: observations}{number \: of \: observations} \\](https://tex.z-dn.net/?f=%20%5Csf%20%5C%3A%20Mean%20%3D%20%20%5Cfrac%7Bsum%20%5C%3A%20of%20%5C%3A%20all%20%5C%3A%20observations%7D%7Bnumber%20%5C%3A%20of%20%5C%3A%20observations%7D%20%20%5C%5C%20)
![\sf \: mean = \frac{3 + 6 + 6 + 7 + 8 + 11 + 15 + 16}{8} \\ \\ \sf \: mean = \cancel \frac{72}{8} \\ \\ \red{\underline{ \boxed{ \sf \: mean = 9}}}](https://tex.z-dn.net/?f=%20%5Csf%20%5C%3A%20mean%20%3D%20%20%5Cfrac%7B3%20%2B%206%20%2B%206%20%2B%207%20%2B%208%20%2B%2011%20%2B%2015%20%2B%2016%7D%7B8%7D%20%20%5C%5C%20%20%5C%5C%20%20%5Csf%20%5C%3A%20mean%20%3D%20%20%5Ccancel%20%5Cfrac%7B72%7D%7B8%7D%20%20%5C%5C%20%20%5C%5C%20%20%20%20%5Cred%7B%5Cunderline%7B%20%5Cboxed%7B%20%5Csf%20%5C%3A%20mean%20%3D%209%7D%7D%7D)
