iscam_twopropztest: iscam_twopropztest Function

In apjacobson/iscam: Introduction to Fundamental Concepts and Various Applications of Statistics

Description

This function calculates a two proportion z-test and/or interval.

Usage

iscam_twopropztest(observed1, n1, observed2, n2, hypothesized = 0,
  alternative = NULL, conf.level = NULL, datatable = NULL)

Arguments

observed1	observed number of successes or sample proportions (assumed if value is less than one)
n1	sample size
observed2	observed number of successes (assumed if value is less than one)
n2	sample size
hypothesized	hypothesized difference in probability of success/population proportions (default is zero)
alternative	form of alternative hypothesis ("less", "greater", or "two.sided")
conf.level	Input confidence level(s) for a two-sided confidence interval.
datatable	Instead of entering the four individual numbers, you can pass in the two-way table of counts. Be sure to label the datatable in this case.

Examples

iscam_twopropztest(6, 17, 12, 20, alternative = "less")
iscam_twopropztest(10, 20, 17, 22, conf.level = .95)
iscam_twopropztest(10, 20, 17, 22, conf.level = c(.90, .95))
