Question

write two conditions of stat change
​

Answer 1

Answer:

The conditions we need for inference on one proportion are:

Random: The data needs to come from a random sample or randomized experiment.

Normal: The sampling distribution of p needs to be approximately normal - needs at least 10 expected successes and 10 expected failures.

Independent: Individual observations need to be independent. If sampling without replacement, our sample size shouldn't be more than 10% of the population.
