In hadiyusri/project3package: Tests Related To Hypothesis Testing, Linear Regression, Cross Validation.

Description

This function calculates values associated to the t-test such as the test statistics, p-value, degree of freedom, and the conclusion on whether we reject or fail to reject the null hypothesis tested from lifeExp data in the gapminder package.

Usage

my_t.test(x, alternative, mu)

Arguments

x	the numeric vector of lifeExp pulled from the gapminder data
alternative	the one-sided or two-sided test
mu	the mean value tested given from the null hypothesis (mu = 60)

Value

A list indicating test statistics, p-value, degree of freedom, and the conclusion on whether we reject or fail to reject the null hypothesis tested from lifeExp data in the gapminder package.

Examples

set.seed(302)
p <- 0.4
flip_coin <- rbinom(100, size = 1, prob = p)
my_t.test(as.numeric(flip_coin), alternative = "greater", mu = p)
