Math Question
![Use technology to construct the confidence intervals for the population variance \( \sigma^{2} \) and the population standard deviation \( \sigma \). Assume the sample is taken from a normally distributed population.
\[
c=0.98, s=31, n=19
\]
The confidence interval for the population variance is (Round to two decimal places as needed.)](https://d3hlidq5bf9vg0.cloudfront.net/app-server-student/2022/1/23/16e76a31-9d0e-4b47-b741-b1b21d53ef78.png "Use technology to construct the confidence intervals for the population variance \( \sigma^{2} \) and the population standard deviation \( \sigma \).
