The amount of lateral expansion (mils) was determined for a sample of n = 6 pulsed-power gas metal arc welds used in LNG ship containment tanks. The resulting sample standard deviation was s = 2.83 mils. Assuming normality, derive a 95% CI for CI for σ2 CI for σ s2 and for o. (Round your answers to two decimal places) mils
