Hypergeometric hypothesis test
Web15 okt. 2024 · Step 3: Decision Rule. Now comes the decision rule. This is where it gets interesting. Remember that the basic principle of hypothesis testing is to assume that H₀ is true. Therefore, we assume that p ≤ 0.5 is true. And, for simplicity of calculations, let’s assume that p=0.5, i.e. the coin is perfectly fair. WebThe hypergeometric distribution is used for sampling without replacement. The density of this distribution with parameters m, n and k (named Np, N-Np, and n, respectively in the …

WebIn your example, the first hypothesis test H 0: μ ≤ 1.5 versus H a: μ > 1.5 you find a p-value of 0.305 which means that your sample does not provide ''evidence'' for H a. This does … WebIn your example, the first hypothesis test H 0: μ ≤ 1.5 versus H a: μ > 1.5 you find a p-value of 0.305 which means that your sample does not provide ''evidence'' for H a. This does however not imply that you can conclude that H 0 is true (it is only not rejected or accepted, but there is no evidence for H 0.
The hypergeometric test uses the hypergeometric distribution to measure the statistical significance of having drawn a sample consisting of a specific number of successes (out of total draws) from a population of size containing successes.
