A binomial hypothesis test starts with a binomial model: a fixed number of trials, two outcomes, independent trials, and a constant success probability ppp. The number of successes is written X∼B(n,p)X \sim B(n,p)X∼B(n,p).
Step-by-step lessons on Edexcel A Level Maths Hypothesis Testing, covering 7.1 Hypothesis Testing, 7.2 Finding Critical Values, 7.3 One-Tailed Tests, and 7.4 Two-Tailed Tests. Each one builds up to exam-style questions. Build fluency with the core pure algebra and calculus toolkit early, since almost every mechanics and statistics topic on the course depends on it.
