We have discovered dead fish floating around our boat. we think that the dead fish are caused by a sudden increase in a red tide algae bloom. what would be a properly written hypothesis for our belief?

Hypotheses are typically written in an "if-then" format. This statement concerning algal increases could be properly written as "if the red algal concentration is higher than usual, then there will be dead fish floating on the surface of the water." These statements allow us to test the belief and see if there are causal links between the two.
