Hypothesis Test on Two Population Variances

Description

Hypothesis Test on Two Independent Normal Population Variances

Usage

var2.test(s1, s2, n1, n2, alp = 0.05, side = "two", dig = 4)

Arguments

s1	Sample standard deviation of population1
s2	Sample standard deviation of population2
n1	Sample size of population1
n2	Sample size of population2
alp	Level of significance, Default: 0.05
side	Type of the alternative hypothesis, Default: 'two'
dig	Number of digits below the decimal point, Default: 4

Value

Test Statistic (F0) and the p-value (pv)

Examples

var2.test(s1=3.5, s2=5.8, n1=25, n2=34)

x = rnorm(20, 199, 4)
y = rnorm(25, 200, 2)
var2.test(sd(x), sd(y), length(x), length(y), side="up")
