Hypothesis as a decision making problem there are four possible outcomes when we conduct a hypothesis test if h0 is not correct, we reject it, we have made the correct decision. If the null h0 is correct and we accept it, we have made the correct decision. If the h0 is correct and we reject is, we have made the wrong decision (we call this type i error) Advice: understand the relationship between confidence levels and error types.
