Hospital personnel routinely examine patient records for error, such as incomplete insurance information, on incomplete patient history, or missing/incomplete medical records. On average, about 300 new patients are admitted each day. Historically, about 2% of these records have contained errors. If a random sample of 50 new patient records is checked each day, what is the probability that this sample will contain at least one patient record with missing information?

Solutions

Expert Solution

Probability that the sample of 50 new patients will contain at least one patient record with missing information is computed as:
= 1 - Probability that that there is no record with missing information

= 1 - (1 - 0.02)50 = 1 - 0.9850 = 0.6358

Therefore 0.6358 is the required probability here.
