What is the value of LCL of EWMA control charts?

A. LCL=\(μ_0+Lσ\sqrt{[\frac{λ}{2-λ}\big\{1-(1-λ)^{2i}\big\}]}\)
B. LCL=\(μ_0-Lσ\sqrt{[\frac{λ}{2-λ}\big\{1-(1-λ)^{2i}\big\}]}\)
C. LCL=\(μ_0-Lσ\sqrt{[\frac{λ}{2-λ}\big\{1-(1+λ)^{2i}\big\}]}\)
D. LCL=\(μ_0+Lσ\sqrt{[\frac{λ}{2-λ}\big\{1-(1+λ)^{2i}\big\}]}\)
Answer» C. LCL=\(μ_0-Lσ\sqrt{[\frac{λ}{2-λ}\big\{1-(1+λ)^{2i}\big\}]}\)
