Explanation / Answer

Using Minitab:

One-Sample T: data

Variable N Mean StDev SE Mean 95% CI
data 5 8.00 12.35 5.52 (-7.33, 23.33)

95% CI with value 5 is

One-Sample T: data

Variable N Mean StDev SE Mean 95% CI
data 5 3.000 1.581 0.707 (1.037, 4.963)

In first sample 30 is the extereme value so 95% CI is  (-7.33, 23.33) which is wider than an 95% CI with value 5 (without the outlier) is (1.037, 4.963).

Hope this will be helpful. thumbs up if it hrlpful. God bless you.
