A manufacturer gets a shipment of 700 batteries of which 60 are defective. The store manager wants to be able to test random samples in future shipments. She tests a random sample of 20 batteries in this shipment to see whether a sample of that size produces a reasonable inference about the entire shipment. The numbers 1‐60 represent defective batteries. She generates this list: 127, 413, 155, 564, 38, 266, 344, 476, 486, 177, 26, 331, 358, 131, 352, 227, 31, 253, 31, 277. Does the sample produce a reasonable inference?
