A normally distributed population has a mean of 500 and standard deviation of 100.

Calculate standard error for the following sample means and sample sizes.

(a) =

(b) =

(c) =

Population Mean	= 500
Population Standard Deviation	? = 100

A normally distributed population has a mean of 500 and standard deviation of 100. Calculate standard error for the following sample means and sample sizes. Population Mean ? = 500 Population Standard Deviation ? = 100 Sample Mean (M) Sample Size (n) Standard Error (?M) 100 4 (a) 100 25 (b) 100 100 (c)

Solution

(a)Standard Error =s/vn= 100/sqrt(4) =50

------------------------------------------------------------------------------------------------------

(b)Standard Error=100/sqrt(25) =20

------------------------------------------------------------------------------------------------------

(c)Standard Error=100/sqrt(100) =10
