What is Scientific hypotheses?
Scientific hypotheses, in general, are the premises within a given theory, which can be validated on the basis of a scientific method, contributing to the formulation of new hypotheses. In this experiment the theory says that cholesterol levels between people who exercise and people who do not exercise is different. Within this theory, the statement says that people who exercise for an hour may have lower cholesterol levels, is a hypothesis that will be confirmed or refuted after the experiment.
The dependent variable is summarized in the phenomena or factors explained or identified, because they are influenced or determined by the independent variable. In this experiment the independent variable is the performance (or not) of exercises. Exercise is what influences or determines cholesterol levels in this study. Thus, cholesterol levels are a dependent variable.
Hence, to check whether a person exercises regularly or not, the scientist can determine the cholesterol level.
