2
for this i added positive got: 12
i added negative and got: 22
do i do 12  22
and get 10
10/8 = 1 2/10 = 1 1/5?? not sure on this one

Your first answers are right.
What is the outlier for the second one? 
the outlier is 16 for question 2

Yes.
10/8 = 1.2
Eliminating 16, the median is ? 
eliminating 16 would be
12 6 = 6 for the mean 
Nope.

eliminating the 16 would be 6
1
3
2
= 6
so 12  6 = 6 as mean w/o 16 outlier 
6/7

,857 is the mean
i messed up
12 + 6 = 6
6 /7
= .857
i forgot a step thanks again and again
.857 is the mean without outlier 16 
You're welcome.
