hypo: Hypothesis Testing

In shunyao643/ab1202ay2021: Basic Statistic Tool for AB1202

Description

hypo returns test statistic (z or t-value), location of x_bar on the graph (relative to centre), which test is used and the corresponding p-value.

Usage

hypo(one_tail = TRUE, unknown_pop_sd = TRUE, x_bar, mu, sd, sample_size)

Arguments

one_tail	boolean value for type of test, e.g. FALSE (defaults to TRUE otherwise)
unknown_pop_sd	boolean, e.g. FALSE (defaults to TRUE otherwise)
x_bar	value, e.g. 30
mu	value, e.g. 32
sd	value, e.g. 3.14
sample_size	integer, e.g. 30

Details

By default, the computation assumes that sample standard deviation is used - if using population standard deviation (where it is known or given), set unknown_pop_sd to FALSE.

Similarly, the computation assumes that the one-tail test is used - if using the two-tail test, set one-tail to FALSE.

Value

Returns the p-value.

Examples

hypo(TRUE, TRUE, 30, 32, 5, 30)
