Based on 20 samples, the average resistance is 25 ohms and the sample standard deviation is 0.5 ohm. Determine the 90% confidence interval of the standard deviation of the batch.
PLEASE SOLVE FOR THE STANDARD DEVIATION, NOT THE MEAN VALUE. I REPEAT< SOLVE FOR THE STANDARD DEVIATION FOR THE CONFIDENCE INTERVAL
We have find the 90% confidence interval of the standard deviation of the sample using Chi-square distribution.
