PKSC 4300 Exam 3 STATISTICAL PROCESS CONTROL IN CONVERTING
1. how are normal distributions related to mean: Mean should be in the middle
2. how are normal distributions related to standard deviation: 68.26% of the data in a
normal distribution will fall between +/- 1 sigma
95.46% will fall between +/- 2 sigma
99.73% will fall between +/- 3 sigma
3. Normal histogram:
4. Bimodal histogram:
5. Neither:
6. Calculate control limits from mean and standard deviation: UCL = mean + 3standard
deviation
LCL = mean - 3standard deviation
7. In control limits:
