## Question

Write a short function that could be used to test whether the observations of a categorical variable are uniformly distributed (meaning all probabilities are equal across categories). (Hint: you can test whether the function works by testing whether the distribution of risk is 1/3:1/3:1/3). Begin the function with the following template:
my.chi.test <- function (x){
#created function goes here
return( list=c("X-squared" = chi, "df" = length(x)-1,
"p-value" = round(value,4)))
}

Solution:

=============================

my.chi.test <- function (x){
#created function goes here
x <- mtcars\$gear
# get unique values
distinct_categories <- unique(x)

# count number of unique values
category_cnt <- length(distinct_categories)

# Expected probability
expected_prob <- 1/category_cnt

# expected count
expected_cnt <- length(x) * expected_prob...
