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%© BrainMass Inc. brainmass.com September 20, 2018, 2:58 pm ad1c9bdddf - https://brainmass.com/math/algebra/variance-on-shelter-sample-data-587948
This solution logically arrives at the right option by performing necessary calculations. Attached in Word.
