a total of 104 manufactured by a machine has sample mean value equals to 26 ohms and known variance 104 ohms square . calculate the 95% confidence interval of the sample mean resistance with three decimals of accuracy.
Added by Becky R.
Step 1
Step 1: Calculate the standard error of the mean using the formula: \[SE = \frac{\sigma}{\sqrt{n}}\] where \(\sigma\) is the known standard deviation (which is the square root of the variance) and \(n\) is the sample size. Show more…

A sample of 15 circuits from a large normal population has a mean resistance of 2.35 ohms. We know from past testing that the population standard deviation is 0.42 ohms. Determine a 99% confidence interval for the true mean resistance of the population. *
