Suppose that an alien lands on Earth and wants to estimate the proportion of humans who are male. Fortunately, the alien had a good statistics course on its home planet, so it knows to take a sample of human beings and produce a confidence interval. Suppose that the alien happened upon the members of Dr. Cortes’s statistics class from fall semester, so it finds 7 males in its sample (there were a total of 38 students).
Use this sample information (with technology) to form, a 95% one-proportion z-confidence interval for the actual proportion of all humans who are female.
