Provides a one-sample hypothesis test. The test assumes that the underlying population is normal and furthermore that σ is known.
one.sample.z(data = NULL, null.mu = 0, xbar = NULL, sigma, n = NULL, alternative = "two.sided", conf = 0.95)
data |
A vector of quantitative data. Not required if |
null.mu |
The expectation for the null distribution. |
xbar |
Sample mean. Not required if |
sigma |
The null distribution standard deviation |
n |
The sample size. Not required if |
alternative |
Type of test. One of three must be specified |
conf |
Confidence level. |
The function can use either raw data is.null(data)==FALSE
or summarized data if is.null(data)==TRUE
. With the later xbar
and n
must be specified by the user.
