Chapter 4: Q. 53 (page 263)

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.

Short Answer

Expert verified

The explanatory variable is calorie consumed by person , response variables is food consumption , the experimental units is amount of pizza , and the treatments is eating 65of either calories of berries or65calories of candy .

Step by step solution

01

Given information

We need to find the explanatory , response variables, the experimental units, and the treatments in this case

02

Explanation

The reaction variable is the point of interest of a query in a look at or experiment. An explanatory variable is one which explains adjustments in that variable.

Here reaction variable is meals intake and explanatory variable is calorie fed on via way of means of person .

Also, experimental devices is quantity of pasta and remedy is consuming of either 65energy of berries or 65energy of candy .

groups. The treatment group would be offered hearing aids, dentures, transportation, and other services not available without charge to the control group. The review board believed that providing these services to some but not other people in the same institution raised ethical questions. Do you agree?

The Willowbrook and hepatitis Bstudies In the 1960s, children entering the Willowbrook State School, an institution for the intellectually disabled on Staten Island in New York, were deliberately infected with hepatitis. The researchers argued that almost all children in the institution quickly become infected anyway. The studies showed for the first time that two strains of hepatitis existed. This finding contributed to the development of effective vaccines. Despite these valuable results, the Willowbrook studies are now considered an example of unethical research. Explain why, according to current ethical standards, useful results are not enough to allow a study.

Dead trees On the west side of Rocky Mountain National Park, many mature pine trees are dying due to infestation by pine beetles. Scientists would like to use sampling to estimate the proportion of all pine trees in this area that have been infested.

a. Explain why it wouldn鈥檛 be practical for scientists to obtain an SRS in this setting.

b. A possible alternative would be to use every pine tree along the park鈥檚 main road as a sample. Why is this sampling method biased?

c. Suppose that a more complicated random sampling plan is carried out, and that 35% of the pine trees in the sample are infested by the pine beetle. Can scientists conclude that exactly 35% of all the pine trees on the west side of the park are infested? Why or why not?

A report in a medical journal notes that the risk of developing Alzheimer鈥檚 disease among subjects who regularly opted to take the drug ibuprofen was about half the risk of those who did not. Is this good evidence that ibuprofen is effective in preventing Alzheimer鈥檚 disease?

a. Yes, because the study was a randomized, comparative experiment.

b. No, because the effect of ibuprofen is confounded with the placebo effect.

c. Yes, because the results were published in a reputable professional journal.

d. No, because this is an observational study. An experiment would be needed to confirm

(or not confirm) the observed effect.

e. Yes, because a 50%reduction can鈥檛 happen just by chance.

One of the better studies of the effect of regular attendance

at religious services gathered data from a random sample of 3617 adults. The researchers then measured lots of variables, not just the explanatory variable (religious activities) and the response variable (length of life). A news article said: 鈥淐hurchgoers were more likely to be nonsmokers, physically active, and at their right weight. But even after health behaviors were taken into account, those not attending religious services regularly still were significantly more likely to have died.鈥� What conclusion can we draw from this study? Explain your reasoning.
