a) LCL=\(3σ_0 \sqrt{\frac{χ_{v,1-\frac{α}{2}}^2}{v}}\)
b) LCL=\(σ_0 \sqrt{\frac{χ_{v,1-\frac{α}{2}}^2}{2v}}\)
c) LCL=\(σ_0 \sqrt{\frac{χ_{v,1-\frac{α}{2}}^2}{v}}\)
d) LCL=\(\frac{σ_0}{2} \sqrt{\frac{χ_{v,1-\frac{α}{2}}^2}{v}}\)
b) LCL=\(σ_0 \sqrt{\frac{χ_{v,1-\frac{α}{2}}^2}{2v}}\)
c) LCL=\(σ_0 \sqrt{\frac{χ_{v,1-\frac{α}{2}}^2}{v}}\)
d) LCL=\(\frac{σ_0}{2} \sqrt{\frac{χ_{v,1-\frac{α}{2}}^2}{v}}\)
