One Sample Test of Proportion

Description

infer_os_prop_test compares proportion in one group to a specified population proportion.

Usage

infer_os_prop_test(
  data,
  variable = NULL,
  prob = 0.5,
  phat = 0.5,
  alternative = c("both", "less", "greater", "all")
)

## Default S3 method:
infer_os_prop_test(
  data,
  variable = NULL,
  prob = 0.5,
  phat = 0.5,
  alternative = c("both", "less", "greater", "all")
)

Arguments

data

numeric vector of length 1 or a data.frame or tibble

variable

factor; column in data

prob

hypothesised proportion

phat

observed proportion

alternative

a character string specifying the alternative hypothesis, must be one of "both" (default), "greater", "less" or "all". You can specify just the initial letter.

Value

infer_os_prop_test returns an object of class "infer_os_prop_test". An object of class "infer_os_prop_test" is a list containing the following components:

n

number of observations

phat

proportion of 1's

p

assumed probability of success

z

z statistic

sig

p-value for z statistic

alt

alternative hypothesis

obs

observed number of 0's and 1's

exp

expected number of 0's and 1's

deviation

deviation of observed from expected

std

standardized resiudals
