In ISCAM: Companion to the Book "Investigating Statistical Concepts, Applications, and Methods"

Rejection Region for Normal

Description

normpower determines the rejection region corresponding to the level of significance and the first probability and shows the normal distribution shading its corresponding region.

Usage

iscamnormpower(LOS, n, prob1, alternative, prob2, verbose = TRUE)

Arguments

LOS	A numeric value representing the level of significance; 0 < LOS< 1
n	A numeric value representing the sample size
prob1	A numeric value representing the first probability
alternative	"less", "greater", or "two.sided"
prob2	A numeric value representing the second probability
verbose	Logical, defaults to TRUE. Set to FALSE to suppress messages

Value

A plot of the normal distribution with the rejection region highlighted.

Examples

iscamnormpower(0.05, n = 100, prob1 = 0.5, alternative = "greater", prob2 = 0.6)
iscamnormpower(0.10, n = 50, prob1 = 0.25, alternative = "less", prob2 = 0.15)
iscamnormpower(0.05, n = 200, prob1 = 0.8, alternative = "two.sided", prob2 = 0.7)
