Answer to Question 1

A

Answer to Question 2

Given 3-sigma control limits for a control chart, there is a 0.0026 (or 0.26) chance that a given sample will fall outside the control limits as the result of random variation alone. (Three-sigma limits include 99.74 of the area under the normal curve).
