Hypothesis testing is based on the idea that we can say things about the population from a sample taken from it
Steps of Hypothesis Testing 1.Decide on yourhypothesis(provide evidence for alternative hypothesis): a.The hypotheses is always about the population parameters, not the sample values or statistics. b.The null hypothesis usually refers to the status quo- the things we are trying to find evidence against. It generally represents no effect. c.A null hypothesis should include a statement of equality and the alternative should not.
