Calculate the standard error for the sampling distribution o

Calculate the standard error for the sampling distribution of the sample proportion approximately normal with n = 13 and n = 69?

Solution

Standard Error of sample means = standard deviation of the source population divided by the square root of n

Normal Distribution has 0 mean and 1 Standard Deviation. So for n = 13

SE of Sample Means = 1 / 13 = .2774

for n = 69

SE of Sample Means = 1 / 69 = .1204
