Hypothesis Test Setup Calculator
Set up and evaluate a complete hypothesis test. Enter your sample data, choose the test type and tail, and get the null/alternative hypotheses, test statistic, critical values, p-value, and conclusion.
Hypothesis testing follows a structured framework:
Steps
- State H₀ (null) and H₁ (alternative)
- Choose α (significance level)
- Calculate test statistic
- Find p-value or compare to critical value
- Make a decision (reject or fail to reject H₀)
Test Statistic: z = (x̄ - μ₀) / (σ/√n) or t = (x̄ - μ₀) / (s/√n)
Decision Rule
- If p-value < α → Reject H₀
- If p-value ≥ α → Fail to reject H₀
