In azc242/collegestats: Common functions used in college statistics classes

Description

This function will find the minimum samples needed to obtain a desired Type II error, or beta. It takes in the significance level, desired Type II error, null hypothesis, actual mean/probability.

Usage

type_2_err_min_size(alpha, beta, H0, Ha, two_sided = FALSE, sigma = NULL)

Arguments

alpha	Probability of Type I error
beta	Probability of Type II error
H0	Null hypothesis
Ha	Actual mean or probability used with beta
two_sided	(Optional) Boolean to determine if it is a 2-sided test or not. Defaults to 1-sided test
sigma	(Optional) Standard deviation. Defaults to NULL, for when H0 and Ha are probabilities and not mean values

Value

NOT rounded minimum sample size needed (generally round upwards for an upper test)
