The null hypothesis states that any effects observed after treatment (or associated with a predictor variable) are due to chance alone. Statistically, the question that is being answered is If these samples came from the same population with regard to the outcome, how likely is the obtained result?
State the null and research hypotheses. As represented by Formula. 11.2, the null hypothesis states that there is no difference between. the means for Group 1 and Group 2. For our purposes, the. research hypothesis, shown in Formula 11.3, states that there is a. difference between the means of the two groups.
