4.7.1 Hypothesis Testing
A hypothesis test uses a sample of data in an experiment to test a statement made about the population. The statement is either about a population parameter or the distribution of the population. The hypothesis test will look at the probability of observed outcomes happening under set conditions. The probability found will be compared against a ...
