  • 1

    How can we test Hypotheses using the Normal Distribution

    By looking at the mean of a sample taken from the whole population

  • 2

    What is the Notation for a Sample Mean

    X̅ ~ N(μ, σ²/n), Where X̅ is the Sample Mean and n is the Size of the Sample

  • 3

    What is the Test Statistic

    The sample mean, X̅

  • 4

    How is the Critical Region/Value found

    By standardising the test statistic, Using the inverse normal function

  • 5

    What is the Equation for standardising the Test Statistic

    For the Sample mean of a normally distributed variable, X̅ ~ N(μ,σ²/n), Z = (X - μ) / (σ / √n)
