If you mean: -11 times (-3 -9) then it is +132
The arithmetic mean of 10, 11, and 6 is 9. Add them together then divide by 3.
To find the mean you add them all up then divide by the number of numbers so: 1+3+5+7+9+11 divided by 6 = 36/6 = 6
If you mean: 12, 11, 9, 6, 2 then the next number is -3 Because they are being reduced by 1, 2, 3, 4 and then 5
9.75

Median of the set = arithmetic mean of 8 and 9 = 8.5
11 1/3 + 6 7/9= 11 1x3/3x3 + 6 7/9= 11 3/9 + 6 7/9= 17 10/9= 18 1/9
There is only one set of data so there is only one mean. Therefore there is no standard error of the mean.
