You want to make a statement about the variability in the costs of personnel shelters. After collecting sample data (cost in $K) on 9 shelters you perform some preliminary calculations.
Given the information provided:
The coefficient of variation is about 17.64%
The variance is about $61.72K
The standard deviation is about $79.36K
The coefficient of variation is about 18.86%
This solution logically arrives at the right option by performing necessary calculations. Attached in Word.
