For some population, the proportion of subjects in a particular class is 40%. 
Considering the sampling distribution of p, answer the following:

a) What percentage of samples of size n=600 would you expect to have a sample 
   proportion less than 35%.

	Since SD(p)=sqrt(0.4*0.6/600)=sqrt(0.0004)=0.02 then
	z=(0.35-0.40)/0.02=-0.05/0.02=-2.5. Hence 0.62% of
	samples of size 600 would result in sample proportions 
	less than 35%.

b) What percentage of samples of size n=100 would you expect to have a sample 
   proportion greater than 40%.

	Since the mean of the sample proportions is 40%, you would
	expect 50% of samples to result in a sample proportion
	greater than 40%.
