nPowerSample: Calculates the sample size for hypotesis tests

In cgu-dados/auditsampling: A auxiliary package to calculate some basic things in sampling. Most used para CGU auditors.

Description

This function calculates de sample size for hypotesys tests considering the following hypotesis:

H_{0}:\text{ } μ \neq μ_{0}

H_{0}:\text{ } \bar{p} \neq p_{0}

H_{0}:\text{ } μ ≤q \text{ or } ≥q μ_{0}

H_{0}:\text{ } \bar{p} ≤q \text{ or } ≥q p_{0}

Usage

nPowerSample(p = NULL, p0 = NULL, mu = NULL, mu0 = NULL,
  sd = NULL, alpha = 0.05, beta = 0.2, alternative = 1)

Arguments

p	Population proportion.
p0	Hypothesized proportion.
mu	Population mean.
mu0	Hypothesized mean.
alpha	Level of significance.
alternative	1 if is a greater/lesser test and 2 for equal/different one.

Value

The sample size.

Examples

nPowerSample(p=0.03, p0=0.05)
nPowerSample(p=0.02, p0=0.05)
nPowerSample(mu=100, mu0=120,sd=24)
nPowerSample(mu=100, mu0=110,sd=24,beta=0.05,alternative = 2)
