We are asked if the distribution given by the following image:
is skewed or if it is approximately symmetric.
We observe that the maximumof the distribution (which expands from 0 to 100) is located at about 50 (right in the center. We also observe that the histogram to the left of 50 looks approximately like the mirror image of the part to the right of 50. This means that the distribution is very close to a symmetric distribution.
There is no skeweness that we can observed in the data. So please select answer B.
