1. A sample of n=22n=22 data values randomlyselected from a normally distributed population hasvariance s2=13.4s2=13.4. Construct a 99% confidence intervalfor the population variance. Round your endpoints to one decimalplace.
2. A sample of n=40n=40 data values randomlyselected from a normally distributed population has standarddeviation s=7.6s=7.6. Construct a 90% confidence interval forthe population standard deviation. Round your endpoints to onedecimal place.
3. A sample of n=27n=27 data values randomlyselected from a normally distributed population has standarddeviation s=4.7s=4.7. Construct a 95% confidence interval forthe population standard deviation. Round your endpoints to onedecimal place.
4.A sample of n=12n=12 data values randomly selectedfrom a normally distributed population hasvariance s2=26.1s2=26.1. Construct a 99% confidence intervalfor the population variance. Round your endpoints to one decimalplace.
