(b)	n = 56, ππ = .43			(Click to select)  Yes  No
(c)	n = 123, ππ = .47			(Click to select)  Yes  No
(d)	n = 578, ππ = .004			(Click to select)  Yes  No

Answer 1

The formula of standard error is

If n* > 5 and n* > 5 we say that normality follow.

		Standard error	Normality
a)	n=27 , = 0.24	0.0822	Yes
b)	n=56, = 0.43	0.0662	Yes
c)	n = 123 , = 0.47	0.0450	Yes
d)	n = 578 , = 0.004	0.0026	No
