Question

The factors that influence the breaking strength of a synthetic fiber are being studied. Several variables were considered and preliminary data suggest that the two primary sources of variation are individual differences in machines and in operators. Four production machines and three operators are chosen and an experiment is run using fiber from the same production batch.

Complete the following questions regarding this experiment:

1) There are ______ factors in this experiment.

2) There are ______levels of variable "operators."

3)The levels of "production machines" ranges from ______ to _____?

Explanation / Answer

(1) There are TWO factors in this experiment.

EXPLANATION:

Factor A: Mchines

Factor B: Operators

(2) There are 3 levels of variable "operators"

EXPLANATION:

Factor A: Production Machnines at 4 Levels

Factor B: Operators at 3 Levels

(3) The levels of "production machines" ranges from 1 to 4.
