Wherever you go, you will be observing human behavior, and it is difficult not to make a judgment about people after observing how they behave. You might consider three people on a crowded bus to be kind if you see them give up their seats so a mother can sit down with her two young children. You might consider a grocery store employee to be rude if you asked him where to find the milk and he rolled his eyes and sighed heavily before directing you to its location. These two judgments would be logical—kind in the first case and rude in the second—because that is the type of people they appeared to be.

However, social psychologists are more concerned with the external social conditions that influence behavior. Maybe only one of the people on the bus acted kindly and the other two gave up their seats because they did not want to be perceived as unkind by others on the bus. Perhaps the grocery store employee is usually kind, but he behaved rudely because he has been told to work an extra shift at the last minute and it means he will likely miss a friend’s birthday party. If you attribute someone’s behavior to her or his personality, your judgment may underestimate the social conditions that influenced the behavior. When explaining the causes of someone’s behavior, underestimating or discounting the social situation results in what social psychologists call an attribution error.

 For your assignment this week, you will look at a scenario and consider how the cause of a person’s behavior may be explained better by situational influences than one’s personality or internal disposition. 

• Review the Learning Resources for this week and consider how the causes of a person’s behavior may be explained by situational factors.
• Consider the following scenario for this Assignment:                                                                              

 Imagine that you have been summoned for jury duty in the United States. If you are selected to be on the jury,     you will be hearing a rape case where a 23-year-old female alleges sexual assault. In order to select the jury (a     process known by the Latin term voir dire), both the prosecutor and defense attorney question the jury pool to identify and dismiss for cause people who have strong opinions about the subject matter, who already know about the case, or who may be biased for or against either party to the trial. Attorneys may also dismiss members of the jury pool who they think will not be favorable to their case. These types of dismissals are called peremptory challenges and the attorneys have a limited number of them.                                                                                                                                             

During the process of jury selection, you notice the prosecutors are using their limited peremptory challenges to dismiss most of the young women from the jury pool. You find this peculiar, given that young women would seem to be most favorable to the prosecution’s case.

Submit 1–2 pages, not including title page and reference page:

• Informed by social psychology theory, explain why the prosecutor was reluctant to seat young women on the jury. Please provide a detailed explanation for this seemingly odd behavior.

In addition to the Learning Resources, search the Walden Library and/or Internet for peer-reviewed articles to support your Assignment. Use proper APA format and citations, including those in the Learning Resources.

MA 260 Statistical Analysis I

Directions: Unless otherwise stated, answer in complete sentences, and be sure to use correct English, spelling, and grammar. Refer to the “Assignment Format” page located on the Course Home page for specific format requirements.

NOTE: Show your work in the problems.

1. A recent article in the Myrtle Beach Sun Times reported that the mean labor cost to repair a color television is $90 with a standard deviation of $22. Monte’s TV Sales and Service completed repairs on two sets this morning. The labor cost for the first was $75 and it was $100 for the second. Compute z values for each and comment on your findings.

2. The mean of a normal distribution is 400 pounds. The standard deviation is 10 pounds.

a. What is the area between 415 pounds and the mean?

b. What is the area between the mean and 395 pounds?

c. What is the probability of selecting a value at random and discovering that it has a value of less than 395 pounds?

3. The monthly sales of mufflers in the Richmond, VA area follow the normal distribution with a mean of 1200 and a standard deviation of 225. The manufacturer would like to establish inventory levels such that there is only a 5% chance of running out of stock. Where should the manufacturer set the inventory levels?

4. Research on new juvenile delinquents revealed that 38% of them committed another crime.

a. What is the probability that of the last 100 new juvenile delinquents put on probation, 30 or more will commit another crime?

b. What is the probability that 40 or fewer of the delinquents will commit another crime?

c. What is the probability that between 30 and 40 of the delinquents will commit another crime?

5. An Air Force study indicates that the probability of a disaster such as the January 28, 1986 explosion of the space shuttle Challenger was 1 in 35. The Challenger flight was the 25th mission.

a. How many disasters would you expect in the first 25 flights?

b. Use the normal approximation to estimate the probability of at least one disaster in 25 missions.
