Webb13 mars 2024 · The probability and hypothesis testing give rise to two important concepts, namely: Null Hypothesis: Result is no different from assumption. Alternate Hypothesis: Result disproves the assumption. Therefore, in our example, if the probability of an event occurring is less than 5%, then it is a biased event, hence it approves the alternate ...
