Working with Large Data Sets
16. Drink and Be Merry? In the paper, "Drink and Be Merry? Gender, Life Satisfaction, and Alcohol Consumption Among College Students" (Psychology of Addictive Behaviors, Vol. 19, Issue 2, pp. 184–191), J. Murphy et al. examined the impact of alcohol use and alcohol-related problems on several domains of life satisfaction (LS) in a sample of 353 college students. All LS items were rated on a 7-point Likert scale that
- a. Obtain normal
probability plots, boxplots, and the standard deviations for the two samples. - b. Based on your results from part (a), which are preferable here, pooled or nonpooled t-procedures? Explain your reasoning.
- c. At the 5% significance level, do the data provide sufficient evidence to conclude that a difference exists in
mean dating satisfaction of male and female college students? - d. Determine a 95% confidence interval for the difference between mean dating satisfaction of male and female college students.
- e. Are your procedures in parts (c) and (d) justified? Explain your answer.
