The amount of lateral expansion (mils) was determined for a sample of n = 8 pulsed-power gas metal arc welds used in LNG ship containment tanks. The resulting sample standard deviation was s = 2.82 mils. Assuming normality, derive a 95% CI for σ² and for σ. (Round your answers to two decimal places.)
