Answer the following True or False: A hypothesis test was conducted to see if a new HIV vaccination reduces the risk of contracting the HIV virus. The implication of a Type II error from the clinical trial is that the vaccination will not be approved when it indeed does reduce the risk of contracting the HIV virus.

The correct answer is - true.

Explanation:

Type I error occurs when the alternate hypothesis is accepted though it is false. A type II error is the failure to reject a false null hypothesis or an alternative hypothesis is rejected even though it is true.

For instance of type II errors: a blood test designed to detect the disease failing to detect the disease in a patient who really has the disease. In the given case vaccination not approved even though reduce the risk of contracting the HIV virus.

Thus, the correct answer is - true.
