3) Let’s always be careful about the CMT 4(A) like the one below
(ex 3) (statistics) What is the standard deviation of 10 numbers?
1) The standard deviation of them is d, then d2-d=0
2) The product of all the 10 numbers is negative
==> In the original condition, the answer is highly likely to be E with 10 variables. If you go with 1) & 2) you get, from d(d-1)=0, you get d=0,1, and in the case of 2) in order for the mulplication of ten numbers to get negative number, there has to be
