Mean.2Pop.Hypothesis: Two Population Means - Hypothesis Test

In AleksandrHovhannisyan/StatisticalInferencesInR: Performs Statistical Inferences in R

Description

Performs a hypothesis test with 100(1-alpha) percent confidence for the difference in the means of two populations

Usage

Mean.2Pop.Hypothesis(xbar1, xbar2, n1, n2, var1, var2,
  differenceInPopulationMeans = 0, popVarKnown = F,
  alternative = "two.sided", equal = "F", alpha = 0.05)

Arguments

xbar1	the sample mean of population 1
xbar2	the sample mean of population 2
n1	the size of the sample from population 1
n2	the size of the sample from population 2
var1	the sample or population variance of population 1 (the latter only if it is known).
var2	the sample or population variance of population 2 (the latter only if it is known).
differenceInPopulationMeans	the hypothesized difference between the population means. Set to 0 by default.
popVarKnown	boolean denoting whether the population variance is known. False by default.
alternative	string denoting the form of the alternative hypothesis Acceptable values are "smaller" (<), "greater" (>), and "one.sided" (=/=).
equal	boolean denoting whether the population variances are equal. False by default. Used only in the case when the population variances are unknown.
alpha	the significance level. Set to 0.05 by default.

Value

The test statistic, p-value, and conclusion of the hypothesis.
