WebFor a left-tailed test 1 - \(\alpha\) is the alpha level. However, if it is a two-tailed test then the significance level is given by \(\alpha\) / 2. The F table is used to find the critical value at the required alpha level. The intersection of the x column and the y row in the f table will give the f test critical value.
