please explain and show steps!!

As a biological consultant, you have been tasked with determining the impact of radiation from a recent water leak from the Fukushima nuclear plant in Japan that had a partial meltdown after the 9.0 magnitude earthquake a few years ago. The concern is the impact on an aquaculture fish farm (raising freshwater cels - Anguilla japonica) 50 km from the plant. Previous studies have found that eels exposed to radiation have reduced swimming speeds. You have notice that some eels have been lethargic (slow moving) over the last couple of days, and that water from the stream draining from the Fukushima plantarea may have been entering into some of the aquaculture ponds that are set up for the cels. Three connected ponds (large, large, and small) hold the eels, and the first large pond is in very close proximity to the potentially contaminated stream. A fourth pond (small) housing eels has no connection to the other ponds, and can act as a control pond for typical cel swim speed. You catch as many cels as you can from each pond and test their swim speed (cm/sec) in a circular swim tank. Any ponds with radiation in the fish will not be shipped as food for the local city. The data are in the SPSS file Eels.say (5 pts). a) What type of test is used to analyze this data? b) What is the null hypothesis? c) Set up the contrast coefficients for as many contrasts as needed to make these evaluations. Have your first contrast determine if pond connectivity is a factor, followed then by contrast(s) to differentiate among pond size and whether the pond might have a stream impact.
