Study Notes
- The significance level is the probability of rejecting the null hypothesis when it is true.
- The p-value is the probability of obtaining the observed result of a hypothesis test, assuming that the null hypothesis is true.
- If the p-value is less than or equal to the significance level, then we reject the null hypothesis.
- If the p-value is greater than the significance level, then we fail to reject the null hypothesis.
