A park ranger wanted to compare the length of largemouth bass in two different lakes in a park. He
randomly pulled 20 largemouth bass from each lake and measured the length of each fish. The
table shows the mean length and the mean absolute deviation (MAD) of the largemouth bass in
each lake

Calculate the means-to-MAD ratio. Can the park ranger conclude that the largemouth bass in Lake
2 are generally longer than the ones in Lake 1?
