a) \(LCL=LSL+\left(Z_δ-\frac{3}{\sqrt{n}}\right) \sigma \)
b) \(LCL=LSL-\left(Z_δ+\frac{3}{\sqrt{n}}\right) \sigma \)
c) \(LCL=LSL-\left(Z_δ-\frac{3}{\sqrt{n}}\right) \sigma \)
d) \(LCL=LSL+\left(Z_δ+\frac{3}{\sqrt{n}}\right) \sigma \)
b) \(LCL=LSL-\left(Z_δ+\frac{3}{\sqrt{n}}\right) \sigma \)
c) \(LCL=LSL-\left(Z_δ-\frac{3}{\sqrt{n}}\right) \sigma \)
d) \(LCL=LSL+\left(Z_δ+\frac{3}{\sqrt{n}}\right) \sigma \)
