Answer:
Patrick's hypothesis was "If fish eat microwaved food, then they will swim faster through the maze."
The fish that are in the control group are the fish without microwaved food.
The independent variable is the microwaved food.
The dependent variable was the time it took for the fish to swim through the maze.
Patrick's conclusion should be that the special food did not seem to make a large difference in helping the fish become faster, since 8 out of 10 fish were faster in both special food and regular food groups.
