Chapter 4: Q. 60 (page 264)

More testosterone Refer to Exercise 56. Could blinding be used in this experiment? Explain your reasoning. Why is blinding an important consideration in this context?

Short Answer

Expert verified

Yes, we can apply blinding because we wouldn't know the genuine placebo effect if we didn't apply blinding, the results of the therapies could be altered by the subject's knowledge of the treatment.

Step by step solution

01

Given information

We need to find can we apply blinding in more testosterone experiment and why is blinding an important consideration in this context.

02

Simplify

In a double-blind experiment, neither the subjects nor the people who measure them know which treatment they had, whereas in a single-blind experiment, either the people who measure or the people who get the results know which treatment they got (but not both).
A testosterone supplement or a placebo is given to the participants.
We may then apply blinding in the experiment by making sure the two options are visually identical and without telling the individuals which treatment they will get.
Furthermore, it is critical to use blinding because otherwise, we will not be able to determine the true placebo effect (as the placebo effect is no longer present when the subjects are aware that they are receiving a placebo) and thus the treatment results may be influenced by the subjects' knowledge.

Frozen batteries Will storing batteries in a freezer make them last longer? To find out, a company that produces batteries takes a random sample of 100 AA batteries from its warehouse. The company statistician randomly assigns 50 batteries to be stored in the freezer and the other 50 to be stored at room temperature for 3 years. At the end of that time period, each battery’s charge is tested. Result: Batteries stored in the freezer had a significantly higher average charge. What conclusion can we draw from this study? Explain your reasoning.

Sampling the forestTo gather data on a 1200-acre pine forest in Louisiana, the U.S. Forest Service laid a grid of 1410equally spaced circular plots over a map of the forest. A ground survey visited a sample of 10%of the plots.

a. Explain how you would use a random number generator to choose an SRS of 141plots. Your description should be clear enough for a classmate to carry out your plan.

b. Use your method from part (a) to choose the first 3plots.

Anonymous? Confidential? Texas A & M, like many universities, offers screening for HIV, the virus that causes AIDS. Students may choose either anonymous or confidential screening. An announcement says, “Persons who sign up for screening will be assigned a number so that they do not have to give their name.” They can learn the results of the test by telephone, still without giving their name. Does this describe anonymous or confidential screening? Why?

Foster care versus orphanages Do abandoned children placed in foster homes do better than similar children placed in an institution? The Bucharest Early Intervention Project found statistically significant evidence that they do. The subjects were 136young children abandoned at birth and living in orphanages in Bucharest, Romania. Half of the children, chosen at random, were placed in foster homes. The other half remained in the orphanages. (Foster care was not easily available in Romania at the time and so was paid for by the study.) What conclusion can we draw from this study? Explain your reasoning.

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.
