Answer:

UCL (x bar) = 424

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) = $\mu+\frac{4\sigma}{\sqrt{n}}$

On substituting the respective values, we get

UCL (x bar) = $400+\frac{4\times30}{\sqrt{25}}$

UCL (x bar) = 424

Similarly,

LCL (x bar) = $\mu-\frac{4\sigma}{\sqrt{n}}$

On substituting the respective values, we get

LCL (x bar) = $400-\frac{4\times30}{\sqrt{25}}$

LCL (x bar) = 376
