Step 1
You are asked to calculate the width, L, of the confidence interval for estimating the population mean under a normal distribution with known population variance. This is to be done for two different scenarios, each with its own confidence level, sample size, and Show more…

Given samples from a normal population with a known variance, find the following: The known variance when n = 100 and the 99% confidence interval for the mean is 23.26 units in width. Show your work in detail. The final answer is counted for little.

Construct the indicated confidence intervals for $(a)$ the population variance $\sigma^{2}$ and $(b)$ the population standard deviation $\sigma .$ Assume the sample is from a normally distributed population. $$c=0.99, s^{2}=0.64, n=7$$
