a.
A completely randomized design for the given experiment is to be described.
a.
Answer to Problem 64E
A completely randomized design is:
Explanation of Solution
A simplest experimental design in terms of the convenience and analysis is well expressed with the help of the statistical term, known as a completely randomized design.
The treatments are randomly assigned from the subject through the use of this design. So, a completely randomized design for the subject of
Conclusion:
Hence, a completely randomized design is well described above.
b.
A random number generator to the treatments assign is to be explained.
b.
Answer to Problem 64E
A random number generator to the treatments assign is listed as:
The subject
The subject
The subject
Explanation of Solution
Given:
Number of subject:
Calculation:
Need to give a every subject a unique integer number from number system as
Here, check every consecutive number of four consecutive numbers. If the first digit is one
And if the number corresponds with a subject then you should choose this subject:
The subject
The subject
The subject
Conclusion:
Hence, random number generator is well described above.
c.
The purpose of the control group for this cash to find work setting is to be explained.
c.
Answer to Problem 64E
The purpose of the control group for this cash to find work setting is to eliminate the outside effects.
Explanation of Solution
A baseline group which receives no treatment or act as neutral treatment then it is known as the control group in an experiment.
To eliminate the outside effects a control group is used. The outside effects are born due to the following cause:
- Chance
- The environment
- The employers
It mostly used for the comparison between two group to result out the best group for the experiment.
Conclusion:
Hence, to eliminate the outside effects a control group is used.
