Answer 1

(A) Type I error is convicting an innocent person.

Explanation:

• A type I error is the rejection of a true null hypothesis.
• A type II error is the non-rejection of a false negative/null hypothesis.

When someone is on trial for suspicion of committing a crime, the hypotheses are:

`H_0` : innocent

`H_A` : guilty

From the given options, A Type I error is convicting an innocent person. If the null hypothesis holds (i.e. a person is innocent) nut we still go ahead to convict the person, we have rejected a true null hypothesis.
