The table to the right includes results from polygraph experiments. In each? case, it was known if the subject lied or? not, so the table indicates when the polygraph test was correct.

The test statistic is:

The p-value:

Did the subject actually lie? No (did not lie) Yes (lied) that subject lied 35 that subject did not lie
