E-drug: Sampling drugstores (cont)
---------------------------------------------
<Could anyone help me to do a sample size determination of drugstores
in my city?>
I intend to determine the prevalence of heart failure using rate of
digoxin sales. The researchers would go to the drugstores to ask use
of that drug.
Thanks in advance
