    What is the Population Parameter for a Hypothesis Test

    The probability, p

  • 2

    What is a Test Statistic

    The result of a test of a random variable

  • 3

    What is the Null Hypothesis, H0

    The Hypothesis that is assumed to be correct

  • 4

    What is the Alternative Hypothesis, H1

    The parameter if your assumption is proven wrong

  • 5

    How is the Null Hypothesis Written

    H0 : p = x

  • 6

    How is the Alternative Hypothesis Written

    H1 : p > x - One tailed test, H1 : p < x - One tailed test, H1 : p ≠ x - Two tailed test

  • 7

    When is the Null Hypothesis rejected

    If the calculated probability is lower than the significance level

  • 8

    When is there Insufficient Evidence to reject the Null Hypothesis

    When the calculated probability is higher than the significance level

  • 9

    What happens to the significance level in a two tailed test

    It is halved
