A manufacturer gets a shipment of 600 batteries of which 50 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 1-50 represent defective batteries.
She generates this list: 33, 413, 28, 564, 38, 266, 344,476,486, 177, 26,331,358, 131, 352, 227,31, 253,31,
277.
Does the sample produce a reasonable inference?
