Dr. Franklin wants to study the accuracy of eyewitness testimony. He will tell his subjects that they will take a paper and pencil test and have them sign forms to agree to participate. He will then tell them he left their test papers in his office and will be back in a few minutes with them. While he is away, one of his research assistants will run into the room and steal something from the professor's desk and run back out again. Dr. Franklin will then come back in, hand out the test papers, and ask the participants to describe the suspect in detail. Dr. Franklin will explain what occurred after he collects the participants' papers. What might an ethics review committee decide about the proposal? (3 points) A:The proposal is approved, as it meets the ethical guidelines defined by the APA. B:The proposal is approved, even though the confidentiality of participants is not protected. C:The proposal is denied, because participants will likely suffer psychological harm. D:The proposal is denied, because participants will likely suffer psychological harm and are not provided informed consent. E: The proposal is denied, because Dr. Franklin intends to deceive participants without debriefing them.

The decision of an ethics review committee about Dr. Franklin's research proposal is:

A:The proposal is approved, as it meets the ethical guidelines defined by the APA.

Explanation:

APA (American Psychological Association) has ethical guidelines for conducting psychological researches.  The most relevant one in this case is: "follow informed-consent rules."  Dr. Franklin clearly ensures that his students give their consents to participate in the eyewitness testimony study by having each sign a form to agree to participate in the research.  I am also sure that the confidentiality and privacy of subjects (students who participate in the research) will be highly protected, in line with another guideline of APA, because these issues have not raised any controversy.

A landscape architect used the entire length of an 80ft rope to lay out a flower

bed in the shape of a square. In another area, he used the entire length of the

same rope to lay out a second flower bed in the shape of a circle.

Perimeter of square = 80 feet Circumference of circle = 80 feet

How many square feet greater is the area of one of the flower beds than the other? (use 3.14 for pi)

:

Area of the square: 20 * 20 = 400 sq/ft

:

Find the radius of the circle using the circumference:

2*3.14*r = 80

r = 80%2F6.28

r = 12.74 ft

:

Find the area of the circle using 13.03 as the radius

A = 3.14*12.74^2

A = 509.6 sq/ft

;

:

509.6 - 400 = 109.6 sq/ft more in the circle
