i think so
I'll check this
Pretty sure by 3.25; I'll have a friend check @jim_thompson5910
thats what i thought
First , figure out
1 on 18, 2 on 38, 1 on 40, 3 on 44, 1 on 46, 1 on 48
and then divide by 1+2+1+3+1+1
that is the original mean
then figure out
and divide by 2+1+3+1+1
that is the new mean
its 42 and 1/3
witch simplifys to 3.25
What did you get for
and what do you get for
the average is the sum of all the numbers (i.e. 360) divided by the number of numbers (i.e. 9)
so the first mean is 360/9 = what ?
now we "toss out the outlier"
which is the number that seems "far away" from the others.
in this case, the 18 seems far away
so now we add up all the numbers 360 take away 18
we get 360-18 = 342
and instead of 9 numbers, we now have 8 numbers.
the new mean is 342/8 = what ?
so old mean was 40, new mean is 42.75
the new mean is bigger by how much ?
