Question

Refer to the sample data for polygraph tests shown below. If one of the test subjects is randomly selected, what is the probability that the subject is not lying? Is the result dlose to the probability of 0.424 for a negative test result? Did the Subject Actually Lie? Positive test results Negative test results No (Did Not Lie) 10 32 Yes (Lied) 47 10 The probability that a randomly selected polygraph test subject was not lying is0 (Type an integer or decimal rounded to three decimal places as needed) Is the result close to the probability, rounded to three decimal places, of 0.424 for a negative test result? A. No, because there is more than a 0 050 absolute difference between the probability of a true response and the probability of a negative test result O B. Yes, because there is less than a 0 050 absolute difference between the probability of a true response and the probability of a negative test result ° C. No, because there is less than a 0 050 absolute difference between the probabilty of a true response and the probablity of a negative test result O D Yes, because there is more than a 0 050 absolute difference between the probability yf a true response and the probability of a negative test result

Explanation / Answer

from above ttotal number of subjects =10+32+47+10=99

henc probability =(10+32)/99=0.424

option B is correct
