19.26 (EX) Detecting genetically modified soybeans 1/2: Most soybeans grown in the United States are genetically modified to, for example, resist pests and so reduce use of pesticides. Because some nations do not accept genetically modified (GM) foods, grain-handling facilities routinely test soybean shipments for the presence of GM beans. In a study of the accuracy of these tests, researchers submitted lots of soybeans containing 1% of GM beans to 23 randomly selected facilities. Eighteen detected the GM beans. Explain why the conditions for the large-sample confidence interval are not met. O The difference between the number of failures and number of successes is not large enough. O The sample size is too large. O The number of failures is smaller than 15. O We cannot be sure that the samples were chosen randomly.
