Dexter is a TV show about Dexter Morgan, a forensic expert who secretly lives a double life as a vigilante serial killer. He works in the Miami Metro Police Department, analyzing blood splatter patterns to solve crimes.
In one case, Dexter runs a forensic test to check if a suspect’s DNA is at a crime scene. He sets up the hypotheses:

Null hypothesis ( H 0 H_0 ) : The suspect’s DNA is not at the crime scene.
Alternative hypothesis ( H 1 H_a ) : The suspect’s DNA is at the crime scene. The test gives a p-value of 0.01 , and Dexter is using a significance level ( α \alpha ) of 0.05 .
What should Dexter conclude?
