What is the 95% confidence interval for 100 ohm resister with 10% tolerence?(adsbygoogle = window.adsbygoogle || []).push({});

Here is my work so far, can someone please tell me if I am doing it wrong or right? Thank you in advance.

from table 95%: k = 1.96

100 * 0.1( which is the 10% tolerance) = 10

10 / sigma >= 1.96

Sigma <= 5.10204

confidence interval limits:

100ohm +- 1.96(5.10204ohms) = 100ohm +- 10ohms
