finitePropSampleSize: Proportion sample size - finite (known) population

In clayford/nandc: Sample Size and Critical Region Calculations (n and c)

Description

Calculate sample size needed to estimate a proportion within a given margin of error for a finite (known) population size.

Usage

finitePropSampleSize(N, moe, p = 0.5, conf = 0.95)

Arguments

N	population size
moe	margin of error expressed as a proportion (0 < moe < 1)
p	estimated proportion (default = 0.5); leave as is for most conservative estimate.
conf	confidence level associated with margin of error (default = 0.95)

Value

Estimated sample size needed to estimate a proportion within a given margin of error for a finite (known) population size.
