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

Mrs. Sue Algebra outlier/mean recheck  Marko, Tuesday, September 27, 2011 at 10:19pm
the outlier is 16 for question 2

Mrs. Sue Algebra outlier/mean recheck  Ms. Sue, Tuesday, September 27, 2011 at 10:28pm
Yes.
10/8 = 1.2
Eliminating 16, the median is ?

Mrs. Sue Algebra outlier/mean recheck  Marko, Tuesday, September 27, 2011 at 10:32pm
eliminating 16 would be
12 6 = 6 for the mean

Nope.

Mrs. Sue Algebra outlier/mean recheck  Marko, Tuesday, September 27, 2011 at 10:46pm
eliminating the 16 would be 6
1
3
2
= 6
so 12  6 = 6 as mean w/o 16 outlier

6/7

Mrs. Sue Algebra outlier/mean recheck  Marko, Tuesday, September 27, 2011 at 10:54pm
,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
