Introduction to estimation - Sampling distribution of a proportion
3 important questions on Introduction to estimation - Sampling distribution of a proportion
For which sampling distribution are the following characteristics of:
1) the mean is equal to the population proportion,
2) the variance is equal to p(1-p)/n,
3) is approximately normally distributed provided that np and n(1 − p) are greater than or equal to 5
