# Question: EarthquaTe Magnitufes 95 confidence n 50 s 0 587 Use

EarthquaTe Magnitufes 95% confidence; n = 50, s = 0.587.

Use the given information to find the number of degrees of freedom, the critical values X2L and X2R, and the confidence interval estimate of s. The samples are from Appendix B and it is reasonable to assume that a simple random sample has been selected from a population with a normal distribution.
