Note: you can copy any of the following symbols from here: p o o2 S It has been reported that the probability that an individual will develop schizophrenia over their lifetime is 0.004. Medical researches selected a random sample of 3000 individuals and determined that 17 of them developed schizophrenia. Is there evidence to support the claim that the true proportion of people who will develop schizophrenia is different from 0.004 at the a = 0.05 level of significance? (Source:...
