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.

Growing in the shade- The ability to grow in shade may help pine trees found in the dry forests of Arizona to resist drought. How well do these pines grow in shade? Investigators planted pine seedlings in a greenhouse in either full light, light reduced to 25% of normal by shade cloth, or light reduced to 5% of normal. At the end of

the study, they dried the young trees and weighed them. Identify the experimental units and the treatments.

Tonya wanted to estimate the average amount of time that students at her school spend on Facebook each day. She gets an alphabetical roster of students in the school from the registrar’s office and numbers the students from 1 to 1137. Then Tonya uses a random number generator to pick 30 distinct labels from 1 to 1137. She surveys those 30 students about their Facebook use. Tonya’s sample is a simple random sample because

a. it was selected using a chance process.

b. it gave every individual the same chance to be selected.

c. it gave every possible sample of size 30 an equal chance to be selected.

d. it doesn’t involve strata or clusters.

e. it is guaranteed to be representative of the population.

Your statistics class has 30students. You want to ask an SRS of 5students from your class whether they use a mobile device for the online quizzes. You label the students 01,02,...,30. You enter the table of random digits at this line: 1445926056314248037165103622532249061181

Your SRS contains the students labeled

a. 14,45,92,60,56

b. 14,31,03,10,22

c. 14,03,10,22,22

d.14,03,10,22,06

e.14,03,10,22,11
