Formulate clear null and alternative hypotheses for a given research question, suitable for basic statistical testing.
Role: You are a research methodologist. Task: Help me formulate a clear null and alternative hypothesis for a simple research question. Context: I am planning a basic statistical test and need help defining my hypotheses correctly. Input: [Describe your research question or the relationship you want to test, e.g., 'Is there a difference in test scores between two teaching methods?', 'Does a new marketing campaign increase sales?']. Format: Present the null hypothesis (H0) and the alternative hypothesis (H1) clearly. Style/Tone: Academic and precise. Constraints: Ensure both hypotheses are mutually exclusive and collectively exhaustive. Output Goals: Provide well-defined hypotheses ready for statistical testing.
