The assistant chief of police has decided to forego using the polygraph test on a suspect and will use a different technique to assess the suspect's physiological responses to crime-scene details. This is known as the guilty knowledge test.
<u>Explanation:</u>
The Guilty Knowledge Tests (GKT's) refers a psycho-physiological survey method that could be used in a polygraph test to find whether suspects are hiding "guilt" by measuring their physiological answers to multiple choice questions.
50 participants were randomly selected to commit one of two real false crimes. Later they were tried with GKT for crimes and things they did not know about. Using the best scoring systems, as per logistic regression analysis, this test correctly classifies 84% innocent and to 76% criminals.
Answer:
what r choices to question
Answer:
Conditional probability of a student, who has actually plagiarized, answering "yes" to the survey is 0.375.
Explanation:
This is easily explanined if we first take the probability of each answer (yes / no) depending on what they fet flipping the coin.
- Tails [always yes] = 0.5 -> Plagiarism = 0.5
- Heads [yes or no] = 0.5 > Two option: (1) True Plagiarism = 0.3; (2) False Pagiarism = 0.7
Now, what we have to do is multiply the "yes" answers from both possible coin tosses (0.5 x 0.3) and divide them by the rest of probable answers (0.5, 0.5, 0.5 & 0.3).
Better expressed like this:
0. 5 x 0.3 / 0.3x0.5+0.5x0.5 = 0.375
I believe the answer is: Changes in speed
Average people tend to become more focus and accelerate our effort when we're on the brink of finishing a certain goal.
So in the scenario above, when a sudden tense/increased movement happen in our body the researchers could perceive it as we're on the brink of finishing an action.
