Number of observations = 9
Response variable = mean fiber amount in Apricots
Total number of variables per line image = 4
Order of variables on a line image:
1. Factor 1 = Lab ID (1 to 9)
2. Response Variable 1 = Number of observations within a lab
3. Response Variable 2 = Mean fiber amount within a lab
4. Response Variable 3 = Standard deviation (of the data) within a lab
Problem Classification: Interlab (1 element)
