  1. A store owner is trying to decide whether he should order equal amounts of four types of milk (skim, 1%, 2%, and whole). To help determine if certain kinds of milk are more popular, he records how many gallons of each kind of milk he sells over the course of a week. His data shows that he sold: 31 gallons of skim milk, 23 gallons of 1% milk, 37 gallons of 2% milk, and 25 gallons of whole milk. The owner is interested in whether the store sells equal amounts of the four types of milk.

  1. Santos et al. (1994) described the pique technique. They claimed that people are more likely to comply with strange requests than with “typical” ones, even if the strange request is larger.

To test this hypothesis, a researcher asked 160 strangers for money. He asked some people if they could spare a quarter, and asked others if they could spare 37 cents. He then recorded how many people gave him the amount requested and how many people did not.

Were people more likely to give the researcher 37 cents than they were to give him 25 cents?

  1. A researcher wants to assess whether students’ level of prejudice predict attitudes toward racial profiling.  As part of a larger survey, students complete two scales pertaining to those variables.  Higher scores on the prejudice measure indicate greater prejudice and higher scores on the profiling scale indicate greater support for racial profiling.  Scores on both measures are obtained from each of 20 students.

Projects

1. A sequential search of a sorted list can halt when the target is less than a given element in the list. Define a modified version of this algorithm, and state the computational complexity, using big-0 notation, of its best-, worst-, and average-case performances.

2. The list method reverse reverses the elements in the list. Define a function amed reverse that reverses the elements in its list argument (without using the method reverse!). Try to make this function as efficient as possible, and state its computational complexity using big-0 notation.

3. Python’s pow function returns the result of raising a number to a given power. Define a function expo that performs this task, and state its computational complexity using big-0 notation. The first argument of this function is the number, and the second argument is the exponent (nonnegative numbers only). You may use either a loop or a recursive function in your implementation. Caution: do not use Python’s ** operator or pow function in this exercise!

4. An alternative strategy for the expo function uses the following recursive definition:

expo(number, exponent)

= 1, when exponent

= 0 = number * expo(number, exponent – 1), when exponent is odd

= (expo(number, exponent // 2))2, when exponent is even

Define a recursive function expo that uses this strategy, and state its computational complexity using big-0 notation.

5. Python’s 1 i st method sort includes the keyword argument reverse, whose default value is False. The programmer can override this value to sort a list in descending order. Modify the selection Sort function discussed in this chapter so that it allows the programmer to supply this additional argument to redirect the sort.

Search Algorithms

Assume that each of the following expressions indicates the number of operations performed by an algorithm for a problem size of n. Point out the dominant term of each algorithm, and use big-0 notation to classify it.

  • a. 2″ — 4n2 + 5n
  • b. 3n2 + 6

For problem size n, algorithms A and B perform n2 and 1/2 n2 + n instructions, respectively. Which algorithm does more work? Are there particular problem si for which one algorithm performs significantly better than the other? Are the particular problem sizes for which both algorithms perform approximatel e same amount of work?

At what point does an n4 algorithm begin to perform better than a Ti algorithm?

Counseling 5 DEALING WITH CONFLICT

Final Paper

You will write a four to five page, double spaced final paper. Remember to look back at your draft paper you turned in during Week/Module Four. You can use that same topic or choose a new topic.

Final Paper Guidelines

Selecting the Topic

On the journey we call, “life,” where do you see yourself and your relationship with others? Are there areas you want to improve and develop a greater awareness of your own patterns of behavior? Is it your self-esteem, your identity, your emotional expression, your communication style, or how you handle conflict? Select at least two-three areas that are most significant to your own growth and development, e.g., your identity development and its impact on personal and interpersonal relationships, or how you manage conflict and your communication style and their impact on your relationships, or how you manage your emotions and their role in developing your personality traits. You have total freedom to choose any of the areas discussed in your textbook. Make this assignment worthwhile to you.

Structure and Organization:

It would be best to include an introduction and to organize your paper in terms of past, present, and future to give it a logical order and a smooth flow.

  • Introduction:

Introduce your theme (s) and why you chose this topic. State clearly what your paper is going to be about. Make sure to highlight your topic sentence. You are expected to elaborate on this area (s) of your life throughout the paper.

  • Past:

Reflect back on your life story and early childhood experiences. Include details that are only pertinent to your theme. When you introduce an idea, ask yourself: How does it relate to my topic sentence? What am I trying to show? This is a good place to introduce and show how have you dealt or been affected by the theme(s) in your life.

  • Present:

Who are you now in relation to the issue(s) you introduced earlier. How are you dealing with this issue(s) now compared with how you dealt with it in the past? What are some of the current event(s) that are impacting the issue(s) presented? Are there any changes to how you view yourself now?

  • Future:

What techniques or coping skills from “Becoming Aware” textbook that you might use to deal with the issue(s) that you presented earlier? What would you do differently now to enhance the quality of your life in regard to this issue(s)? What are your goals, hopes and visions of yourself? In other words, if you were to re-write your life story, what would you do differently? This part of your paper is about bringing a resolution to the issue (s) of your earlier concern (s).
