I hope it the answer is for you

Answer 2

Heya , heres your answer below:

we took 5 obseavation so the mean is :

addition of all the observation / number of observation = mean

x+x+ 4+x+8+x+12+x+16/5=13

5x+40/5= 13                                      

x+ 8= 13

x=5

by putting the values in evey observation we can find the mean.
