When is there a risk of a Type II error?

Solution

Whenever a researcher fails to reject the null hypothesis.

A type II error fails to reject (accepts) the null hypothesis, although the alternative hypothesis is the true state of nature. It confirms an idea that should have been rejected, claiming that two observances are the same, even though they are different.So,whenever the decision is \"fail to reject H0\" then Type II error occurs.
