I have a sample of 8 datapoints with a Std. Dev of 0.0195940953204932 and Mean of 0.10125 and Confidence Level(95%) value of 0.0163810736238815

I used the Descriptive Statistics Tools in Excel to arrive at this values. This exercise was carried out to calculate the USL and LSL for this mean. I used the Formula as below

USL = Mean + Confidence Level(95%) = 0.117631074

LSL = Mean - Confidence Level(95%) = 0.084868926

But my next step is to bring the USL and LSL to the following desired value of USL = 0.160032286

LSL = 0.042467714

Is this possible with this set of data? How can I modify the Confidence Level(95%) value in order to get this desired values?

Your help is highly appreciated. Thanks in advance.
