In the notation X∼N(μ,σ2)X \sim N(\mu, \sigma^2)X∼N(μ,σ2), what do the two parameters represent?
- μ\muμ: the median
- σ2\sigma^2σ2: the standard deviation
- μ\muμ: the mean
- σ2\sigma^2σ2: the variance
- μ\muμ: the variance
- σ2\sigma^2σ2: the mean
- μ\muμ: the standard deviation
- σ2\sigma^2σ2: the mean
The Normal Distribution Flashcards
Flashcards for Edexcel A Level Maths The Normal Distribution, covering the key formulae, methods and definitions you need to recall for Paper 1, Paper 2 and Paper 3. 21 cards drawn from 3.1 The Normal Distribution, 3.2 Finding Probabilities for Normal Distributions, 3.3 The Inverse Normal Distribution Function, 3.4 The Standard Normal Distribution, 3.5 Finding the mean and standard deviation, 3.6 Approximating a Binomial Distribution, and 3.7 Hypothesis Testing with the Normal Distribution, matched to the Edexcel A Level Maths (9MA0) specification. Recall questions account for roughly 50% of marks at A Level Maths, so these target the marks you can secure before the paper starts.
