A hypothesis is a testable statement or educated guess about the relationship between variables. In this story, Manuel observed a problem (mice pests causing decreased rice harvest and high prices) and then implemented a solution based on his assumption that these actions would solve the problem. His hypothesis can be stated as: "Mixing 20g bait phosphorus material into the soil, placing a scarecrow on the farm, and planting peppermint between rice crops will reduce mice pests and increase rice harvest." This is a testable prediction as its effectiveness can be observed and measured.
