Problem Set 1: Chi Square Test of Goodness of Fit

Research Scenario: A school social worker at a middle school wants to examine whether there is a difference in the number of children who have experienced bullying in different grades (6^th – 8^th). Assume the total number of children in each grade is about equal. He administers a survey on which students self-report whether or not they have been bullied. He is only interested in the number of “yes” responses from students who report being victims of bullying. He records the frequencies of “yes” answers in the table below.

Using this table, enter the data into a new SPSS data file and run a Chi Square Test of Goodness of Fit to test whether the frequencies of being bullied are equal across the different grades. Remember to weight cases as shown in the presentation. Create a bar chart to show the relationship between the variables.

1. Paste SPSS output.  

2. Write an APA-style Results section based on your analysis. Include your bar chart as an APA-style figure as demonstrated in the APA writing presentation. This section is the most important! Thank you!

Deep River College is a two-year school in Southern California. Twice a year, the fundraising office at Deep River mails requests for donations to the alumni. The staff uses a word processing program and a personal information database to create personalized letters. Data on past contributions and other alumni information, however, is stored manually. The dean, Alexandra Ali, recently submitted a systems request asking the college’s IT department to develop a computerized alumni information system. The school does not have a formal systems review committee, and each department has an individual budget for information services. Eddie Bateman, a systems analyst, performed a preliminary investigation and he concluded that the system met all the feasibility tests. After reading his report, Alexandra asked him to proceed with the systems analysis phase.

(1) Design a questionnaire to learn how the current process works and what the information requirements for the new information system would be. Your questionnaire should include the three types of questions discussed in the textbook.

It should contain:

six closed-ended questions, five opinion questions, and one question requesting an explanation of a procedure or problem.

[Hint: use the one question to explain the procedure, and close-ended questions to learn the information requirements]

There are 4 members of the Smith family. They are as follows: Mom; college professor of Mathematics, 45 years old, described by her co-workers as introverted, driven and serious, considered Head of the Household and breadwinner of the family. Dad: works in the oil field, home every two weeks for two weeks and then gone again for the following two weeks, high school drop-out, 40 years old, considerably overweight therefore is contemplating retirement and starting a new business with less wear and tear on his body. Greg: 21 years old, last year of college/fraternity life, athlete who struggled with grades his entire life and not motivated to get a job yet – will most likely move back in with his parents after he graduates. He also suffers from insomnia and takes drugs to ‘self medicate’. Emma: 16 year old in the band in high school, slightly overweight, Honor roll student her entire life and wants to attend Harvard like her mother did (she even started talking and walking earlier than ‘normal’ – such an overachiever!).

What are the dynamics of this family? Choose at least 5 concepts to talk about.

Gender Selection The Genetics & IVF Institute conducted a clinical trial of the YSORT method designed to increase the probability of conceiving a boy. As of this writing, 291 babies were born to parents using the YSORT method, and 239 of them were boys. Use a 0.10 significance level to test the claim that the YSORT method is effective in increasing the likelihood that a baby will be a boy. Find critical value(s), state the conclusion.

a. 1.23; H 1 fail to reject, Support Original claim

b. 2.33; Reject H 1 and Reject H0

c. 2.33; H 1 rejected, Support Original claim

d. 1.96; H 1 fail to reject, Support Original claim

Carefully read the " Interpretation" section of the instructions before answering questions
does the proposed Conclusion follows or Conclusion does not follow the information.

Information: In a certain city where school attendance laws are strictly enforced, it was found that only 15 percent of the students had a perfect attendance
record during a single school semester. Among those who sold newspapers, however, 25 percent had a perfect attendance record during the same semester.

Suppose you have two individuals in a town, Ben and Jerry, deciding over their consumption of ice-cream and fireworks. Further suppose that the price, as well as the additional cost of producing both goods is $1. Assume that Ben and Jerry have the same preferences. If we left it up to Ben and Jerry, would we get the optimal provision of fireworks? Explain and show your answer.

4.) Determine whether the following probability experiment is a binomial experiment. If the probability experiment is not a binomial experiment, state why?

a.) In a town with 400 citizens, 100 randomly selected citizens are asked to identify their religion. The number who identify with a Christian religion is recorded.

b.) An experiment is conducted in which a single die is cast until a 3 comes up. The number of throws required is recorded.
