Does anyone know a formula or syntax for SAS(if we can do it here) that
I can use to find a p-value when comparing the prevalence of a disease in
a sample to the prevalence of the disease in the population when n for the
sample is known but I do not know the standard deviation of the sample or
population?
Thanks a lot
