Chapter 1, Problem 65CRE
Yoga and High-Risk Adolescents Can mindful yoga have a beneficial impact on alcohol use in high-risk adolescents? Read excerpts from the research published in The Journal of Child and Family Studies and answer the questions that follow. (Source: Fishbein et al., “Behavioral and psychophysiological effects of a yoga intervention on high-risk adolescents: A randomized control trial,” Journal of Child and Family Studies, vol. 25 [February 2016]: 518-529, https://doi.org/10.1007/s10826-015-0231-6)
Abstract: We designed a 20-session mindful yoga intervention for adolescents attending a school for students at high risk of dropping out. The 69 participants were randomly assigned to control and intervention groups. Survey data were collected before and after the yoga curriculum. At the post test, students in the yoga condition exhibited trends toward decreased alcohol use as compared to control students.
a. Identify the treatment variable and the response variable.
b. Was this a controlled experiment or an observational study?
c. Based on this study, can you conclude that yoga caused a decrease in alcohol use? Why or why not?

Worker Fatigue. A study by M. Chen et al. titled “Heat Stress Evaluation andWorker Fatigue in a Steel Plant” (American Industrial Hygiene Association, Vol. 64, pp. 352–359) assessed fatigue in steelplant workers due to heat stress. Among other things, the researchers monitored the heart rates of a random sample of 29 casting workers. A hypothesis test is to be conducted to decide whether the mean postwork heart rate of casting workers exceeds the normal resting heart rate of 72 beats per minute (bpm).
a. determine the null hypothesis.
b. determine the alternative hypothesis.
c. classify the hypothesis test as two tailed, left tailed, or right tailed.

Title of the article: After Menopause, Weight Affects Breast Cancer Rates More than Mammography Use
Women who are overweight or obese after menopause face an increased risk of breast cancer, but a large prospective cohort study indicates that the frequency of mammography use and screening accuracy are not the primary explanations for higher rates of breast cancer in these women. The same is true of large, invasive breast cancer tumors and advanced stage disease; risk increases with weight, but higher rates are not explained by the frequency or accuracy of screening mammography before breast cancer was diagnosed. The study appears in the December 3 Journal of the National Cancer Institute.

Test the claim that the amount of smoking is independent of seat belt use. A plausible theory is that people who smoke more are less concerned about their health and safety and are therefore less inclined to wear seat belts.

- Angioplasty is a medical procedure in which an obstructed blood vessel is widened. In some cases, a wire mesh tube, called a stent, is placed in the vessel to help it remain open. The article “Long-term Outcomes of Patients Receiving Drug-eluting Stents” (A. Philpott, D. Southern, et al., Canadian Medical Association Journal, 2009:167–174) presents the results of a study comparing the effectiveness of a bare metal stent with one that that has been coated with a drug designed to prevent reblocking of the vessel. A total of 5320 patients received bare metal stents, and of these, 841 needed treatment for reblocking within a year. A total of 1120 received drug coated stents, and 134 of them required treatment within a year. a) Find a 98% confidence interval for the differences between the proportions for drug coated stents and bare metal stents. b) Suppose that additional patients are to be treated in order to increase the precision of the confidence interval.

- Impact of Arts Education. A randomized controlled experiment involving over 10,000 students enrolled in 4th to 8th grade in Texas examined the impact of arts education on a wide variety of outcomes.' Arts education included visual arts, music, dance, and theater. Six different outcomes were measured over 12 different groups, for a total of 72 different hypothesis tests conducted to examine evidence for a positive impact from additional arts education. "Bowen D and Kisida B, "Investigating Causal Effects of Arts Education: Experimental Evidence from Houston's Arts Access Initiative," Research Report, Kinder Institute for Urban Research, February 12, 2019. (a) If additional arts education has no effect, how many of the 72 tests would you expect to be significant at the 5% level just by random chance? How many at the 1% level?

Previous studies have shown that urban bus drivers have an extremely stressful job, and a large proportion of drivers retire prematurely with disabilities due to occupational stress. In the paper, “Hassles on the Job: A Study of a Job Intervention With Urban Bus Drivers” (Journal of Organizational Behavior, Vol. 20, pp. 199–208), G. Evans et al. examined the effects of an intervention program to improve the conditions of urban bus drivers.Amongother variables, the researchers monitored diastolic blood pressure of bus drivers in downtown Stockholm, Sweden. The data, in millimeters of mercury (mm Hg), on the WeissStats site are based on the blood pressures obtained prior to intervention for the 41 bus drivers in the study.
