Question

If  = 23 ounces,σ = 0.4 ounces,and n = 16,the ±3σ control limits will be

Quizplus · Accepted Answer

The ±3σ control limits can be calculated as follows:
Upper control limit = 23 + (3 x 0.4) = 23.2
Lower control limit = 23 - (3 x 0.4) = 22.8
Therefore, the ±3σ control limits will be 22.8 to 23.2 ounces, which is closest to option C) 22.70 to 23.30 ounces.

If = 23 Ounces,σ = 0
