Scientists test hypotheses using the scientific method. First, there is a question posed about a phenomenon. Then, the hypothesis is created about what the scientist thinks will happen when it is tested. Next, the scientist will create an experiment that will answer the question.
Hypothesis testing-Steps â¢ Steps to do a two-tailed test of the hypothesis that Î² 1 6= 0 :1. Set up the hypotheses:H 0: Î² 1 = 0H a: Î² 1 6= 0 .2. Compute the test statistic:t =b 1 â0Std.tat 328 - Fall 2004 5. Hypothesis testing (contâd) â¢ We can test any hypothesis that might seem appropriate for theapplication at hand. For example, we might wish to testH 0: Î² 1 = 250H a: Î² 1 1 â250ÏË b 1 and the rest is the same as in the one-tailed test described earlier.
