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 close to the probability of 0.430 for a negative test result? Did the Subject Actually Lie? No (Did Not Lie) Yes (Lied) Positive test results 12 37 Negative test results 27 10 The probability that a randomly selected polygraph test subject was not lying is. (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 0.430 for a negative test result? because there is Va 0.050 absolute difference between the probability of a true response and the probability of a negative test result. less than exactly more than

42 What is the difference between a probability sample and a nonprobability sample? Which type is necessary if we wish to statistically generalize from the sample to the population?

Refer to the sample data for pre-employment drug screening shown below. If one of the subjects is randomly selected, what is the probability that the test result is a false positive? Who would suffer from a false positive result? Why? Pre-Employment Drug Screening Results Positive test result Negative test result Drug Use Is Indicated Drug Use Is Not Indicated Subject Uses Drugs 37 12 Subject Is Not a Drug User 1 29 ..... The probability of a false positive test result is (Round to three decimal places as needed.)

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 close to the probability of 0.427 for a negative test result? No (Did Not Lie) Yes (Lied) Positive test results 17 46 Negative test results 34 13 Did the Subject Actually Lie? The probability that a randomly selected polygraph test subject was not lying is (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 0.427 for a negative test result? because there is a 0.050 absolute difference between the probability of a true response and the probability of a negative test result.
