WebNov 4, 2024 · If alpha = 0.10, then it’s 10% on one side. If it’s two-tailed, then you need to split that 10% into two–5% in both tails. Hence, the 5% in a one-tailed test is the same as a two-tailed test with an alpha of 0.10 because that test has the same 5% on one side (but there’s another 5% in the other tail). It’s similar for CIs. WebTo calculate the upper and lower limits of the interval, take the positive critical value and multiply it by the standard error of the mean. Then take the sample mean and add and subtract that product from it. Lower Limit = Sample Mean – (CV * Standard Error of the Mean) Upper Limit = Sample Mean + (CV * Standard Error of the Mean)
