I am having trouple understanding level of significance. One homework question asks the p-value for a hypothesis test is 0.0153. What is your course of action at the 5% level of significance? Do not reject the null hypothesis. or reject the null hypothesis in favour of the alternative hypothesis. or reject the alternative hypothesis in favour of the null hypothesis. Can you explain how to work out this question? Thanks
