You plan to take a random sample of 1000 undergraduate students enrolled at the University of Washington to compare the proportion of female and male students who would like to see that the United States of America have a female President. Suppose that you use random numbers to select students, but you stop selecting females as soon as you have 100, and you stop selecting males once you have 100. Is the resulting sample a simple random sample? Explain your...
