ssize: Determine minimum sample size
In whSample: Utilities for Sampling

ssize takes a population size and returns a sample size

1	ssize(N, ci = 0.95, me = 0.07, p = 0.5)

`N`	The population size
`ci`	The desired confidence interval (default is 0.95)
`me`	The margin of error (default: +/- 0.07)
`p`	The expected rate of occurrence (default: 0.50)

Returns the estimated minimum sample size, rounded up to the nearest integer.

ssize uses a normal approximation of the hypergeomtric distribution approach.

1 2	ssize(1000) ssize(1000, ci=0.90, p=0.60)
