Question 636974: On an exam with a mean of M =82, you obtain a score
of X =86.
a. Would you prefer a standard deviation of s =2 or
s =10?

You can put this solution on YOUR website!
Is s = 2 then z+score+=+%2886+-+82%29%2F2+=+2
If s = 10 then z+score+=+%2886+-+82%29%2F10+=+0.4
The z score is higher when the standard deviation is s = 2.
Your ranking is higher when s = 2.
