Guided Notes

3 key concepts

  • 1

    The null hypothesis states that a change has no effect, while the alternative hypothesis suggests the change does have an effect.

  • 2

    The p-value is the probability of obtaining a statistic at least as far from the mean as the one observed, assuming the null hypothesis is true.

  • 3

    If the p-value is less than the significance level (alpha), you reject the null hypothesis and have evidence for the alternative hypothesis.
