Web12 May 2005 · First attempt at creating a shaded area in R. Not that bad, but we can make it better than that. We just have to create a sequence of vertices between the two extrema of the density (f(-3) and f(-2) here), so that the larger number of vertices gives us a better approximation. In order to accomplish that we are going to use the seq() function ... WebRejection region is considered as the crucial part of the testing process. For the hypothesis testing, the researcher, first, collects the sample data and the next step is to determine the test statistic. For example, consider a case of rejection region in the chi-square test.

WebWe did something called a two-tailed test. This is called eight two-tailed test. Because frankly, a super high response time, if you had a response time that was more than 3 standard deviations, that would've also made us likely to reject the null hypothesis. So we were dealing with kind of both tails.
