Question

PART B 31. A maker of fabric for clothing is setting up a new lif clothing is setting up a new line to "finish" the raw fabric. The line will metal rollers or natural bristle rollers to raise the surface of the fabric; a dyeing cycle time of either 30 minutes or 40 minutes, and a tempe minutes or 40 minutes: and a temperature of either 150° or 175° Celsius. An m will compare all combinations of these choices. Three specimens of fabric will be subjected to each treatment and scored for quality. (A) (i) What is the response variable? (ii) What are the experimental units (or individuals)? (iii) What is the factor, or what are the factors? (iv) How many treatments are there? (B) Briefly explain how to set up the experiment. You should make clear where the basic principles of design enter your experiment. You should also include a diagram that outlines your experiment.

please give accurate answers

Answer 1

a)
i) response variable is quality of fabric
ii) experimental units = three specimens of fabric

iii) there are 3 factors
{line, dyeing cycle time and temperature}

iv) number of treatmenr = 2 * 2 * 2
= 8   {there are 2 levels foe each factor}

Number of individuals = 3 * 8 = 24
