OneSampleMean.Equality: One Sample Mean Test for Equality

Description

H0: margin is equal to 0 Ha: margin is not equal to 0

The test is finding whether there is a difference between the mean response of the test \(\bar{x}\) and the reference value \(\mu_0\)

Usage

OneSampleMean.Equality(alpha, beta, sigma, margin)

Arguments

alpha

significance level

beta

power = 1-beta

sigma

standard deviation

margin

\(margin=\bar{x}-\mu_0\)

the difference between the true mean response of a test \(\bar{x}\) and a reference value \(\mu_0\)
