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

0.485

for a negative test result? Consider the result close if the absolute difference is less than 0.050.

	No (Did Not Lie)	Yes (Lied)
Positive test results	13	38
Negative test results	36	12

(Type an integer or decimal rounded to three decimal places as needed.)

Part 2

Is the result close to the probability, rounded to three decimal places, of

0.485

for a negative test result? Consider the result close if the absolute difference is less than 0.050.

Yes,

No,

because there is

exactly

less than

more than

a 0.050 absolute difference between the probability of a true response and the probability of a negative test result.
