Solution

Yes, there is a difference in sizes of Mangrove snapper in the site G and Site J of the Saint Johns River. Given data indicates that
1. Smallest i.e. from smallest to size of 10 Site G has around 13 fish and none in that size range. Smallest fish in site G is 5 and at the site, J is 15. The largest fish in site G is 30 with 6 fish between the size range 25-30.
In site J the largest fish is 45.

The total study population of site G and J is 25 and the median size for site G is 16.4. I the case of site J the median size is 27.4 (no of fish x size 5 + no of fish x size 10.. )/ total no of fish.
The results indicate that around 21 fish out of 25 are above size 25 in site J taking 25 as the median size that accounts to 84%. For site G 19 out of 25 are below the size 25 i.e. 76%.
