Suppose a large population has mean �� and standard deviation �� , and a simple randomsample of size n is taken. the sampling distribution of the sample mean ! has meanand variance, respectively, equal to

What would  you  expect to see in terms of the behavior of a  sample  proportion of females (p-hat) ifrandom samples  of  size  100 were  taken  from the  population  of all part-time college students? as we saw therefore we can conclude that p-hat is approximately a normal  distribution  with  mean  p = 0.6 and  standard deviation.
