Question
I know I'm reading too much into this, but is the answer C? It does appear to be bell-shaped.
Refer to the data set below (body mass index of men) and determine whether the requirement of a normal distribution is satisfied. Assume that this requirement is loose in the sense that the population distribution need not be exactly normal, but it must be a distribution that is basically symmetric with only one mode.

Is the requirement of a normal distribution satisfied?
A.
No. The points in the normal quantile plot do not lie close to a straight line.
B.
No. The histogram of the data is not bell shaped. There is also more than one outlier.
C.
Yes. The points in the normal quantile plot exhibit some systematic pattern that is not a straight-line pattern.
D.
Yes. The points in the normal quantile plot lie reasonably close to a straight line
Thank you!
