Chapter 4.2, Problem 52E

(a)

To determine

To list the factors in this experiment and state how many levels each factor has.

Answer to Problem 52E

The factors: line, dyeing cycle time and temperature.

Explanation of Solution

It is a study of the experiment of setting of a new line to “finish” the raw fabric by the maker of fabric. Thus, the factors of this experiment are: Line using either metal rollers or natural-bristle rollers to raise the fabric, dyeing cycle time with two levels $30$ minutes or $40$ minutes and temperatures with two levels. Each of the factors has two levels of the experiment the fabric company will do on the three specimen of fabric.

(b)

To determine

To find out how many treatments were included in the experiment if the researchers used every possible combination.

Answer to Problem 52E

The treatments: there are eight.

Explanation of Solution

It is a study of the experiment of the telephone surveys whether the people respond to it or not. There are eight treatments in this study in the question. The various treatments in this experiment are that metal rollers with one of the dyeing cycle time and one of the temperature and then it is used with the other temperature and dyeing cycle time and the same will occur for the natural bristle rollers with two different temperatures and two different cycle times. These are the treatments if the researchers used every possible combination in the study.

(c)

To determine

To list two of the treatments.

Answer to Problem 52E

The treatments: metal rollers with the $40$ minutes dyeing cycle time and the natural bristle rollers with the $40$ minutes dying cycle time.

Explanation of Solution

It is a study of the experiment of the telephone surveys whether the people respond to it or not. The two treatments in this experiment are: metal rollers with the $40$ minutes dyeing cycle time and the natural bristle rollers with the $40$ minutes dying cycle time. As the treatments are the experiments we tend to offer on the objects in the study.
