Question options:
A)
Data appears to be distributed normally (unimodal with mean and median roughly equivalent); one outlier exists (383); no discernable skew
B)
Data appears NOT to be distributed normally (unimodal but mean appears to be less than median); one outlier exists (383); skew to left is discernable and supports relationship of mean to median
C)
Data appears to be distributed normally (unimodal with mean and median roughly equivalent); no outlier exists; no discernable skew
D)
Data appears NOT to be distributed normally (unimodal but mean appears to be greater than median); one outlier exists (383); skew to right is discernable and supports relationship of mean to median
I picked C but was wrong.
