Does the frequency distribution appear to be roughly a normal distribution?
A.
No, although the distribution is approximately symmetric, the frequencies do not start low, increase to some maximum frequency, then decrease.
B.
No, although the frequencies start low, increase to some maximum, then decrease, the distribution is not symmetric.
C.
No, the distribution is not symmetric and the frequencies do not start off low.

Explanation / Answer
The frequency distribution is given by
The frequency distribution is normal because the distribution is not symmetric and thr frequencies do not start off low.
i.e., Option C is correct
No, the distribution is not symmetric and the frequencies do not start off low
