The right-hand "tail" of the standard normal curve can be defined as the part
that lies at least 2 standard deviations to the right of the mean. The left-hand
"tail" can be defined as the part that lies at least 2 standard deviations to the
left of the mean.
According to the empirical rule, approximately what percentage of the area
under the whole curve is in the two tails? (Hint: Find the percentage for each
tail individually.) Round your answer to the nearest tenth.
A. 2.5%
B. 32%
C. 5%
D. 16%
