WebAs mentioned before, methods of making inferences about parameters are either estimating the parameter or testing a hypothesis about the value of the parameter. In this lesson, we will introduce the concepts of hypothesis testing. Then we will discuss hypothesis testing for a population proportion. WebAlthough the sampling distribution for proportions actually follows a binomial distribution, the normal approximation is used for this derivation. ... We want to test the hypothesis \(H_0: \,\, p = p_0\) \(H_a: \,\, p \ne p_0\) with \(p\) denoting the proportion of defectives. Define \(\delta\) as the change in the proportion defective that we ...

TLMaths - O2: Binomial Hypothesis Testing

WebTo hypothesis test with the binomial distribution, we must calculate the probability, p p, of the observed event and any more extreme event happening. We compare this to the level of significance α α. If p > α p > α then we do not reject the null hypothesis. If p < α p < α we accept the alternative hypothesis.
