Answer

Providence's variation is bigger.

Work Step by Step

Coefficient of variation=$\frac{standard \ deviation}{mean}$ By using the results from before: $cv_{JV}=\frac{standard \ deviation}{mean}=\frac{0.4767}{7.15}=0.0667=6.67$% $cv_{P}=\frac{standard \ deviation}{mean}=\frac{1.8216}{7.15}=0.2548=25.48$% Hence providence's variation is bigger.
