Describe the sampling distribution of p. Assume the size of the population is 30,000
n=1400, p=0.444
Determine the mean of the sampling distribution of p.
mean=? (round to three decimal places as needed)
Determine the standard deviation of the sampling distribution of p.
std dev.=?? (round to three decimal places as needed)
Solution
Given that,
p = 0.444
1 - p = 0.556
n = 1400
The mean of the sampling distribution of proportion is ,
= p = 0.444
The standard deviation of the sampling distribution is ,
=
[p(
1 - p ) / n =
[(0.444 * 0.566) / 1400] = 0.420
