Posted by stat on Sunday, September 6, 2009 at 5:17pm.

ok there was a question that my teacher told me i got wrong

the question asked me to compute the mean which I did...

then the question went on to tell me compute the mean with another observation equal to zero

then the part that he drew the line through was my response to this question

Write a sentence about the effect of the zero on Joey\'s quiz average that mentions this property...

my response

The property that this illustrate of the mean is the observations. Sense the number of observations increased but the sum of the observations stayed the same this brough down the mean by defintion...

ok he drew a line threw it and told me it was wrong so my question is how is this wrong?

What would a correct answer include?

Thanks for any Help!
