tpowerg2: Graphs a Two Sample T-Test

In austinragotzy/mathstat: Introduction to Mathematical Statistics R Package

Description

Graphs the power of the one-sample, two-sided $t$-test for the mean. The hypothese are:
H0: mu = mu0 vs. H1: mu != mu0.
See Example 8.3.2 on page 492 for discussion of this test andits power. Exercise 8.3.5 continues the discussion.

Usage

tpowerg2(mu0, sig, n, alpha = 0.05, byv = 0.1)

Arguments

mu0	a number, null population mean null value
sig	a number, population standard deviation usually greater than 1
n	an integer, sample size
alpha	a number, the signifigance level, defaults to 0.05
byv	a number, increment in sequence for mu 1, defaults to 0.1

Value

gammas vector of powers from power function
