Get MoreBut for large n the hypergeometric distribution is approximately binomial (i.e. it is not so likely that you will select the same person twice). Since p = .53 and n = 1100, np > 5 and n (1 – p) > 5, and so we can approximate the distribution as a normal distribution. We will also use the sample p as an estimate of π in calculating the ...

Get MoreWhen you test a hypothesis about a population, you can use your test statistic to decide whether to reject the null hypothesis, H0. You make this decision by coming up with a number, called a p-value. A p-value is a probability associated with your critical value. The critical value depends on the probability you are […]
Get Morep. If the sample size is less than 30 (n30), we consider this a small sample size. When the sample size is small, we use the t-distribution to calculate the p-value.

Get MoreAs a general rule, the binomial distribution should not be applied to observations from a simple random sample (SRS) unless the population size is at least 10 times larger than the sample size. To find probabilities from a binomial distribution, one may either calculate them directly, use a binomial table, or use a computer.
