Answer

Brief Explanations:

A Type 1 error occurs when the null hypothesis ($H_0$) is true but is rejected. Here, $H_0$ is that the person is healthy. So a Type 1 error means the person is healthy but the test says they are infected. A Type 2 error occurs when the alternative hypothesis ($H_A$) is true but the null hypothesis is not rejected. Here, $H_A$ is that the person is infected, so a Type 2 error means the person is infected but the test says they are healthy.

Answer:

For Type 1 error: The person is healthy, but the test says they are infected. For Type 2 error: The person is infected, but the test says they are healthy.
