Choose the correct answer below.
OA.
Yes, because the frequencies start low, proceed to one or two high frequencies, then
increase to a maximum, and the
distribution is not symmetric.
B. Yes, because the frequencies start low, proceed to one or two high frequencies, then
decrease to a low frequency, and the distribution is approximately symmetric.
O C. No, because the frequencies start low, proceed to one or two high frequencies, then
decrease to a low frequency, and the distribution is not symmetric.
D. NO, because the frequencies start low, proceed to one or two high frequencies, then
O D.
decrease to a low frequency, and the distribution is approximately symmetric.
