   2. 0.3432
   3. 0.0000
   4. 0.6568

3. If a control chart shows special causes of variation it may exhibit:
   1. At least one data point above the upper control limit
   2. No points above the upper control limit or below the lower control limit
   3. At least eight consecutive points above the center line
   4. Both A and C are correct
