The Wall Street Journal reported that the age at first startup for 20% of entrepreneurs was 29 years of age or less and the age at first startup for 80% of entrepreneurs was 30 years of age or more.

(a)	Suppose a sample of 200 entrepreneurs will be taken to learn about the most important qualities of entrepreneurs. Show the sampling distribution of p where p is the sample proportion of entrepreneurs whose first startup was at 29 years of age or less. If required, round your answers to four decimal places.
	np =
	n(1-p) =
	E(p) =
	σ(p) =
(b)	Suppose a sample of 200 entrepreneurs will be taken to learn about the most important qualities of entrepreneurs. Show the sampling distribution of p where p is now the sample proportion of entrepreneurs whose first startup was at 30 years of age or more. If required, round your answers to four decimal places.
	np =
	n(1-p) =
	E(p) =
	σ(p) =
(c)	Are the standard errors of the sampling distributions different in parts (a) and (b)?
