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 … Web1 Your problem is that you are subtracting the full standard deviation from the mean. When you do that, it means that you are multiplying the standard deviation by 2, since you are subtracting 1 ∗ s t d ( x) and adding 1 ∗ s t d ( x). Instead, add/subtract 1 2 ∗ s t d ( x). Thus, your new normals are: l o w e r N o r m a l = 26.82 − 41.16 2 = 6.24
