Most penguin species are not sexually dimorphic, which means that there are no obvious outward body characteristics which indicate gender. therefore, penguin gender must be determined by a blood test. a penguin researcher is interested in estimating the proportion of females in a large penguin population. she takes a random sample of n = 20 penguins, and determines the gender of each one using a blood test. shefinds 12 males and 8 females. let π be the proportion of females in the population. compute a numerical point estimate of π.
