Answer:
(A)Barnsboro Bank has more variation.
Step-by-step explanation:
The coefficient of variation of a set is given by the following formula
[tex]CV = \frac{S}{M}[/tex]
In which M is the mean and S is the standard deviation.
The higher the coefficient, the higher the variation of the set.
Barnsboro National Bank
[tex]M = 315, S = 87[/tex]
So
[tex]CV = \frac{S}{M} = \frac{87}{315} = 0.276[/tex]
Wellington S&L
[tex]M = 8350, S = 1800[/tex]
So
[tex]CV = \frac{S}{M} = \frac{1800}{8350} = 0.216[/tex]
The Barnsboro National Bank has the highest coefficient, so it has more variation.
The correct answer is:
(A)Barnsboro Bank has more variation.
