Given the following research topic, answer the question below: Are there differences in university GPA and persistence rates between who enrolled in first-year seminars compared to those who did not enroll in first-year seminars?

a. What is the dependent variable(s)?

b. Are there any other dependent variables that might be of interest in this study?

c. What is the independent variable? Identify levels of the variable.

d. Why is this an example of ex post facto research?

e. Consider the extraneous variable high school (HS) GPA. Describe how you could control this extraneous variable through ANCOVA.

f. Consider the extraneous variable academic major. Describe how you could control this extraneous variable through homogeneous grouping.

g. Consider the extraneous variable campus living arrangement. Describe how you could control this extraneous variable through homogeneous grouping.

h. Suggest one additional extraneous variable and one way to control it.

1. A researcher wishes to examine the relationship between wage earned and educational level of workers. For a sample of 4000 workers she has data on hourly earnings (measured in SAR), age of the worker (in years), worker’s gender, years of experience, number of years with the present employer, size of the firm in which the worker is employed, and highest educational qualification (with 4 classifications: no qualification, secondary school certificate, bachelor degree or PhD)

1. Explain how you would set up a model to address the researcher’s key interest.
2. Based on your model, how would you estimate the predicted impact on wages of holding a PhD compared to having a bachelor’s degree.
3. If the researcher uses ln(wage) as the dependent variable, how would the estimated coefficients be interpreted?
4. What general advice would you give the researcher in relation to her work – eg. what econometric issues should she be aware of in conducting this research and interpreting the results?

     The mean height of a random sample of 47 students who take part in athletic activities at NRDC is 175cm with a standard deviation of 5cm while a random sample of 132 students who showed no interest in athletics had a mean of 170cm and a standard deviation of 7cm.

(a) Construct a 99% confidence interval for the difference in the mean heights of the two groups of students.

(b) Are students who take part in athletic activities taller? Test at the 1% level of significance.

Susan is beginning to plan college savings accounts for her two children. Her son Bobby is 8 and will begin college in 10 years when he turns 18. Her daughter Mallory is 2 and will begin college in 16 years when she is 18. Susan plans to deposit $10,000 per year starting next year into a joint account that earns 8.0% annually. Her last deposit will occur in the year that Bobby starts school. If Bobby’s schooling costs $25,000 each year for four years, and Mallory’s schooling costs $30,000 each year for four years, will Susan’s plan provide enough money for both her children’s college education? By how much will Susan meet/miss the goal when she quits depositing money in year 10? (Assume schooling costs are paid after the year is completed, i.e. Bobby’s first tuition payment will occur at end of year 11)

An 8-year male is brought to the Emergency Department for a temperature of 105 F and extreme lethargy. The child complains of a sore throat, severe headache, and severe body aches. The parents state the child went to bed in a healthy condition but woke during the night with a temperature of 102. The child has no other significant medical history. The parents do not believe in vaccinations and home school their children. They have one other child at home who has asthma. The patient is diagnosed with influenza and the plan is to admit to the pediatric intensive care unit. The nurse returns to the patient to prepare for transfer to PICU and hears the UAP telling the parents they are smart not to vaccinate their children because it caused his son to have autism.

Craft an initial post that addresses:

1. What ethical dilemma does the nurse face and what interventions should the nurse take to address the issue(s)?  
2. Provide a detailed education plan for the rationale for vaccinations and the management of influenza.

Think back to your experience in grades 1-6 and using the theories of Erikson, Piaget, Vygotsky, Bandura, and Kohlberg answer the following questions:: How would you describe your social competence as a young child? Did it change over middle childhood? Were you a high or a low status child then? Did you play predominantly with high or low status children? Were you popular? Think of a popular child in your school and an unpopular child (first names only). Describe the popular child. Make sure you consider the characteristics that contributed to this child's popularity. How do these characteristics compare with popular child characteristics you read about in your text? Describe the unpopular child. Make sure you consider the characteristics that contributed to this child's unpopular status. How do this child's characteristics compare with unpopular child characteristics you read about in your text?
