Suppose that there exists the population below and that you happen to know the population standard deviation (you can calculate it in this case).If you draw a sample which has these four observations,19, 21, 7, 25 what is the z value?Answer to four decimal places. DO NOT USE ANY PREVIOUSLY ROUNDED ANSWERS AS INPUTS IN YOUR CALCULATIONS;

Population values: 5, 16, 7, 33, 19, 21, 30, 6, 8, 14, 25.
