LCL (x bar) = 376
Step-by-step explanation:
Given:
Average calories contained, μ = 400
Standard deviation, σ = 30 calories
Sample size, n = 25
a) UCL (x bar) =
On substituting the respective values, we get
UCL (x bar) = 
or
UCL (x bar) = 424

LCL (x bar) =
On substituting the respective values, we get
LCL (x bar) = 
or
LCL (x bar) = 376
