Final answer:
Without the number of employees tested, we cannot calculate how many are accused of lying from a 90% accurate polygraph test. However, we can infer that 10% could be falsely accused due to the inaccuracy rate. Polygraph tests may not always be reliable indicators of deception due to subjective interpretations and false positives.
Step-by-step explanation:
To answer the question of how many employees are accused of lying based on the polygraph test that is 90% accurate, we would need additional information such as the number of employees tested. Since this is not provided, we cannot calculate the number of employees accused of lying without making assumptions. However, we can discuss the implications of the polygraph's accuracy hypothetically.
If, for example, 100 employees were tested and the polygraph is known to be 90% accurate, we can assume that out of 100 tests, 90 would be accurate. If all employees claim not to use drugs, and we assume none of them do, this could potentially mean 10 employees might still be incorrectly identified as lying due to the test's 10% inaccuracy rate. This example demonstrates the limitations and risks associated with relying on polygraph tests to make decisions about honesty.
It's important to note that polygraph tests measure physiological responses, and the interpretation of these responses can be subjective and may not always reliably indicate deception. High stress levels, nervousness, and various other factors can lead to false positives, where honest individuals are accused of lying.
