Question
three experiments tested for a difference in means between a control and treatment group. Here are the results Experiment A: 95% CI for -Ha = (-0.34, 1.22), p = 0.12 Experiment B: 95% CI for 1-Hz = (-3.77, 4.65), p 0.57 For both statistical tests, the null hypothesis was that there is no difference in population means. Suppose two statisticians are discussing how to interpret the results. The first statistician, Carla, says that Experiement B provides stronger support for the null being true, because the p-value is larger. The second statistician, Diana, disagrees and says that Experiement A provides stronger support for the null being true. What do you think Diana's argument is?Explanation / Answer
Diana's arguement is correct
since
Decision rule : if p value is small then then there is strong support to alternative
Actual decision : p value = 0.12 which is smaller than p = 0.57
So Experiment B provides stronger support to null
