Question: Assume that social intelligence, measured on a scale
of 1 to 10, is normally distributed in a population. A sample of 12
randomly selected participants is drawn. If one is asked to guess
the social intelligence scores of those 12 individuals, which of
these is a reason why the best strategy would be to guess the
population mean every time?
A. The sample will be bimodal; thus, the mean is the least
extreme value.
B. The middle value is the unique value that can be chosen.
C. Guessing the middle value will allow for smaller errors on
average.
D. The score at the midpoint has half the error of the other
possible values.
