A polygraph test is conducted, and the findings indicate that there is an 80 percent chance of deception. What does this mean for the investigation?

The suspect is guilty and should be arrested for the crime.

The suspect might be guilty, but more information is needed from other parts of the investigation.
There has been a mistake in the polygraph test, and the test should be conducted again to get better results.
