About Hypothesis Testing

Hypothesis testing is a statistical method used to make decisions using experimental data.

Null Hypothesis (H₀): Default assumption (no effect)
Alternative Hypothesis (H₁): What you want to prove
p-value: Probability of observing the data if H₀ is true
Significance Level (α): Threshold for rejecting H₀ (typically 0.05)
Test Statistic: Calculated value compared to critical value
