Can I estimate a binomial (success vs failure) as a normal distribution with a sample size of 25 (lower than 30 depended by CLT)?
Homework Answers
We can use normal approximation to binomial distribution for following conditions.
i) n * p >= 5
ii) n (1- p) >= 5
Where n = sample size and p is probability of success.
We have to consider both n and p here.
If both conditions are satisfied, use normal approximation,

If a sample size is greater than 30, which of the following characteristics of the distribution of sample means is true? a.) Nothing can be assumed about the distribution of sample means. b.) The sample size needs to be increased by 10% so we can apply the Central Limit Theorem. c.) The distribution of sample means has a binomial distribution. d.) The distribution of sample means is approximately normal.
