Does the frequency distribution appear to have a normal distribution? explain. Choose the correct answer below. No, because the frequencies start low, proceed to one or two high frequencies, then decrease to a low frequency, and the distribution is approximately symmetric. Yes- because the frequencies start low, proceed to one or two high frequencies, then increase to a maximum, and the distribution is not symmetric. 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. no. because the frequencies. then decrease to a low frequency, and the distribution is not symmetric.

Solution

Remember that the normal distribution has a bell shape, that is, low at first, going up to the peak, then down again.

OPTION C: yes, because the

1. Frequencies start low (the left tail of the distribution)

2. Proceed to one or two high frequencies (near the peak)

3. Decrease to a low frequency (going down after the peak)

4. and the distribution is approximately symmetric (as you can see, the numbers to the left and right of 15 are almost equal.

Thus, it is OPTION C.
