Question: After a recent tornado blew down his street, Carlos encountered a serious health problem. Consider the following hypotheses:

Ho: Carlos will be blind for the rest of his life.

H1: Carlos will regain his sight eventually (perhaps 5 years later?).

His wife, Gaby, needed to react to these two possibilities. If she performs a hypothesis test and makes a Type II error, what would Gaby believe is the truth? What would be the actual truth?
