Chapter 4: Q. 52 (page 263)

A maker of fabric for clothing is setting up a new line to 鈥渇inish鈥� the raw fabric. The line will use either metal rollers or natural-bristle rollers to raise the surface of the fabric; a dyeing-cycle time of either 30or40minutes; and a temperature of either 150掳Cor175掳C. Three specimens of fabric will be subjected to each treatment and scored for quality.

a. List the factors in this experiment and state how many levels each factor has.

b. If the researchers used every possible combination to form the treatments, how many

treatments were included in the experiment?

c. List two of the treatments.

Short Answer

Expert verified

a. The factors in this experiment are Roller type, dyeing-cycle time, temperature and quality of fabric

b. The treatments were included in the experiment are three

c. Two of the treatments are Any combination of metal or natural-bristle roller, and30/40dyein

Step by step solution

01

Part (a) Step 1: Given information

We need to find that List the factors in this experiment and state how many levels each factor has.

02

 Part (a) Step 2: Explanation

The elements on this test are -

The reaction variable is the focal point of a query in a examine or test. An explanatory variable is one which explains adjustments in that variable.

Explanatory variables is Roller type, dyeing cycle time and temperature

Response variables= Quality of the fabric

03

Part (b) Step 1: Given information

We need to find that the researchers used every possible combination to form the treatments, how many treatments were included in the experiment

04

 Part (b) Step 2: Explanation

There are total of three treatments , that are -

Any combination of metal or natural-bristle roller,30/40dyein and 150/175 temperature

05

Part (c) Step 1: Given information

We need to find that two of the treatments .

06

Part (c) Step 2: Explanation

Here two of treatment are :

First one is Any combination of metal or natural-bristle roller,

And second one is30/40 dyein .

Running red lights An SRS of 880 drivers was asked: 鈥淩ecalling the last

ten traffic lights you drove through, how many of them were red when you entered the

intersections?鈥� Of the 880 respondents, 171 admitted that at least one light had been red.

A practical problem with this survey is that people may not give truthful answers. Explain

the likely direction of the bias.

Doctors and nurses Nurse-practitioners are nurses with advanced qualifications who often act much like primary-care physicians. Are they as effective as doctors at treating patients with chronic conditions? An experiment was conducted with 1316patients who had been diagnosed with asthma, diabetes, or high blood pressure. Within each condition, patients were randomly assigned to either a doctor or a nurse-practitioner. The response variables included measures of the patients' health and of their satisfaction with their medical care after 6months.50

a. Which are the blocks in this experiment: the different diagnoses (asthma, diabetes, or high blood pressure) or the type of care (nurse or doctor)? Why?

b. Explain why a randomized block design is preferable to a completely randomized design in this context.

c. Suppose the experiment used only diabetes patients, but there were still 1316subjects willing to participate. What advantage would this offer? What disadvantage?

Want a snack- Can snacking on fruit rather than candy reduce later food consumption? Researchers randomly assigned12women to eat either65 calories of berries or 65calories of candy. Two hours later, all 12women were given an unlimited amount of pasta to eat. The researchers recorded the amount of pasta consumed by each subject. The women who ate the berries consumed133 fewer calories, on average. Identify the

explanatory and response variables, the experimental units, and the treatments.

Sampling stuffed envelopes A large retailer prepares its customers鈥�

monthly credit card bills using an automatic machine that folds the bills, stuffs them into

envelopes, and seals the envelopes for mailing. Are the envelopes completely sealed?

Inspectors choose 40envelopes at random from the 1000stuffed each hour for visual

inspection. Identify the population and the sample.

Can a vegetarian or low-salt diet reduce blood pressure? Men with high blood pressure are

assigned at random to one of four diets: (1) normal diet with unrestricted salt; (2)

vegetarian with unrestricted salt; (3) normal with restricted salt; and (4) vegetarian with

restricted salt. This experiment has

  1. one factor, the type of diet.
  2. two factors, high blood pressure and type of diet.
  3. two factors, normal/vegetarian diet and unrestricted/restricted salt.
  4. three factors, men, high blood pressure, and type of diet.
  5. four factors, the four diets being compared.
