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
[tex] \sf \: Mean = \frac{sum \: of \: all \: observations}{number \: of \: observations} \\ [/tex]
[tex] \sf \: mean = \frac{3 + 6 + 6 + 7 + 8 + 11 + 15 + 16}{8} \\ \\ \sf \: mean = \cancel \frac{72}{8} \\ \\ \red{\underline{ \boxed{ \sf \: mean = 9}}}[/tex]
Hence
