Answer 1

Answer:

a. count of observations that meet a condition (counts), total number of observations (nobs), Hypothesized value of population proportion (value).

Explanation:

In other to use the proportion_ztest method, the need to make import from the statsmodel module ; statsmodels.stats.proportion.proportions_ztest ; this will allow use use the Z test for proportion and once this method is called it will require the following arguments (count, nobs, value=None, alternative='two-sided', prop_var=False)

nobs = number of observations

count = number of successes in the nobs trial or the number of successes for each independent sample.

Value = hypothesized value of the population proportion.
