P-value for proposed mean of a population (known sigma)

Source: R/pval_z.R

Calculates the p-value for a proposed mean for a population with known standard deviation, using the Z-statistic (normal distribution).

pval_z(x, sig, n, mu = 0, side = c("two", "one"))

Arguments

x

Sample mean
sig

Population standard deviation
n

Sample size
mu

Population mean
side

To either get a two-tail or one-tail p-value (Default is "two")

Value

P-value

Examples

x <- 2.6
sig <- 0.3
n <- 36
mu <- 2.5
pval_z(x, sig, n, mu)

#> [1] 0.0455
