Determine the upper-tail critical value
WebWhat is a Critical Value? A critical value defines regions in the sampling distribution of a test statistic. These values play a role in both hypothesis tests and confidence intervals. … WebAug 6, 2024 · To find the T critical value in R, you can use the qt () function, which uses the following syntax: qt (p, df, lower.tail=TRUE) where: p: The significance level to use df: The degrees of freedom lower.tail: If TRUE, the probability to the left of p in the t distribution is returned. If FALSE, the probability to the right is returned.
