Answer: Khan rejected the null hypothesis when it was actually true
A Type I error occurs when we reject the null hypothesis when it is actually true. This is also known as a false positive. In hypothesis testing: - **Type I error (α)**: Rejecting H₀ when H₀ is true - **Type II error (β)**: Failing to reject H₀ when H₀ is false The correct answer is D because the question explicitly states that Albert Khan's analysis suffers from a Type I error, which means he rejected the null hypothesis when it was actually true.
