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 ranged from 1 (strongly disagree) to 7 (strongly agree). On the WeissStats site you will find data for dating satisfaction, based on the results of the study. Use the technology of your choice to do the following.

  1. a. Obtain normal probability plots, boxplots, and the standard deviations for the two samples.
  2. b. Based on your results from part (a), which are preferable here, pooled or nonpooled t-procedures? Explain your reasoning.
  3. 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?
  4. d. Determine a 95% confidence interval for the difference between mean dating satisfaction of male and female college students.
  5. e. Are your procedures in parts (c) and (d) justified? Explain your answer.

The article “Developing a Tool to Measure the Factors Influencing Nurses' Enjoyment of Nursing” (L. Wilkes, M. Doull, et al., Journal of Clinical Nursing, 2016:1854–1860) reports that in a sample of 124 nurses, 54 said that a busy workload had a positive effect on their enjoyment of their job. Can you conclude that less than 45% of nurses feel that a busy workload has a positive effect on their enjoyment of their job?
Is status related to a student’s understanding of science? The article “From Here to Equity: The Influence of Status on Student Access to and Understanding of Science” (Culture and Comparative Studies [1999]: 577– 602) described a study on the effect of group dis- cussions on learning biology concepts. An analysis of the relationship between status and “rate of talk” (the num- ber of on-task speech acts per minute) during group work included gender as a blocking variable. Do you think that gender is a useful blocking variable? Explain.
Medication Usage In a survey of 3005 adults aged 57 through 85 years, it was foundthat 81.7% of them used at least one prescription medication (based on data from “Use ofPrescription and Over-the-Counter Medications and Dietary Supplements Among OlderAdults in the United States,” by Qato et al., Journal of the American Medical Association, Vol.300, No. 24). a. How many of the 3005 subjects used at least one prescription medication? b. Construct a 90% confidence interval estimate of the percentage of adults aged 57 through85 years who use at least one prescription medication. c. What do the results tell us about the proportion of college students who use at least oneprescription medication?
