Determine the standard error of the mean for each of the following:

A) A random sample of 100 persons whose blood pressure has been measured when the known standard deviation is 2.5 mm hg

B) A random sample of 38 men when the known standard deviation for height is three inches

C) A random sample of 65 persons who are waiting in an ER when the known standard deviation for waiting time is 10 minutes

D) The LEB for 16 countries randomly selected from the SWC sheet of the file Chpt 4-1.xls when the countries on the sheet represent the entire population of countries ( consider using the finite population correction)
