A store receives a shipment of 5,000 MP3 players. In a previous shipment of 5,000 MP3 players, 300 were defective. A store clerk generates random numbers to simulate a random sample of this shipment. The clerk lets the numbers 1 through 300 represent defective MP3 players, and the numbers 301 through 5,000 represent working MP3 players. The results are given. 2,789 613 100 4,631 3,472 639 2,270 191 4,490 3,768
Based on this sample, how many of the MP3 players might the clerk predict would be defective?
The manager would expect defective players in the shipment.
