The p-value(which should be smaller than the critical value of the F statistic in order to have a significant test) is normally the area beneath the right tail of the f distribution at the F-value, if I understood the concept correctly. With respect to the regr...
The use of a chi-square table that we will examine is to determine a critical value. Critical values are important in bothhypothesis testsandconfidence intervals. For hypothesis tests, a critical value tells us the boundary of how extreme a test statistic we need to reject the null hypothesis....
