Learning Objective
I can perform a hypothesis test to evaluate a claim about a population.
- 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.
