Chapter 22 hypothesis testing test of a claim about. 1 state a null hypothesis and an alternative a parameter hypothesis based on the claim null hypothesis statement of equality alternative hypothesis statement of inequality. I a also choose a significance level significance level probability cutoff value. 2 get a sample take measurements and summarize then in a statistic called a test statistic. 3 determine the probability of getting a test statistic at least as extreme as the one you got in step 2 assuming the null hypothesis is true find the p value. 4 state the decision and write a conclusion.
