Use the given degree of confidence and sample data? to find a confidence interval for the population standard deviation σ. Assume that the population has a normal? distribution. Round the confidence interval limits to the same number of? decimal places as the sample standard deviation.

Heights of mature White Pine trees: 99% confidence; n = 29, [tex]\frac{}{x}[/tex] = 65 ft , s = 8.4 ft

8.27 ft < σ < 8.53 ft
4.23 ft < σ < 10.47 ft
6.22 ft < σ < 12.59 ft
5.73 ft < σ < 10.07 ft
