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