Explanation / Answer
Correct option:
a. the data are skewed
EXPLANATION:
Out of the 4 facilities, Postal alone has frequency of 18, which is 56.25%. So, the data is positively skewed, i.e., extreme data results are larger. The mean will be larger than the median. Thus, it is inappropriate to calculate the mean or median type of facility.
