7. Eureka or Not? Suppose that twenty identical experiments are taking place simultaneously around the world. The researchers are all studying the same drug, which they hope will improve the survival rate of the black-winged peckerwood finch after it has been infected with a particular type of tree mold. The survival rate for those left untreated is unfortunately only 32%. None of the researchers know about the others' work. The table below shows the results from the 20 different studies. In all cases, the Type I error rate was a = 0.05 and the hypothesis being tested was: H : ps 0.32 H : p > 0.32
